Physics of the Moon :: physics science space

Gravitational Force of Bodies All bodies with mass exert a gravitational pull on the bodies around them, even you and me. The larger the radius and mass of the body the larger the force. Most people know that the force of gravity on earth is much greater than on the moon, but how much larger is it, and how is gravity calculated? German astronomer Johannes Kepler (1576-1630) spent years observing the motion of planets and developed a set of laws for planetary motion. Years after his death Physicist Isaac Newton (1642-1727) used these laws to help him develop his law of universal gravitation. The law of Universal Gravitation states that: "every particle in the Universe attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them" (Serway 424). This essential means that the force of gravity increases the larger the masses are and decreases the farther away the masses are. The formula to determine the the magnitude of the gravitational force is: Fg = G (M1M2)/R^2 G is the Universal Gravitational Constant, M1 and M2 is the mass of the two objects and R is the distance between them. On Earth the force of gravity causes all objects to accelerate at 9.8m/s^2. For example, say you have a mass of 1kg on the surface of the earth. The force of gravity between the two objects is given by: Fg= (6.673x10^-11)(5.9736x10^24)(1) (6.3781x10^6)^2 Fg = 9.8 m/s^2 6.672x10^-11 is the value of the universal gravitational constant (G), 5.9736x10^24 is the mass of the Earth (M1) in kg, 1 is the mass of our object on the earth's surface (M2) in kg, and 6.3781x10^6 is the distance between the center of the Earth and the Earth's surface (R) in meters. 9.8 m/s^2 is the acceleration force between objects and the earth On the moon this value is much less because the moon has a smaller mass and radius. If the same 1kg object is on the surface of the moon, the force of gravity on it is given by: Fg = (6.673x10^-11)(7.349x10^22)(1) (1.7381x10^6)^2 Fg = 1.6 m/s^2 7.349x10^22 is the mass of the moon in kg and 1.7381x10^6 is the radius of the moon in meters. On the moon objects experience roughly 1/6 the gravitational force they would on Earth. Two astronuats are playing catch on the moon. They throw and catch the ball at a height of 1.

Why Can’t We Be More Like Canada? :: Essays Papers

Why Can’t We Be More Like Canada? The National Rifle Association has gone too far in defending the right to bear arms because the safety of schools is in jeopardy. The tragic events that occurred at Columbine High School in early 1999 with the killing of 13, including 12 students and one teacher while wounding many more, put much greater focus and awareness on violence in schools. The upward trend of violence in schools beginning in the early 1990’s got national attention because of the shootings that took place just outside of Denver. The tragedy at Columbine seemed to be the last straw for anti-gun activists, politicians, the media, and parents of children in schools to take action to protect America’s young from death in a place where kids are supposed to be safe. The NRA is not stepping back from their fight to protect the second amendment, but changes need to be made to protect kids growing up in society today. School violence, especially school shootings, has kept pace in recent years since the Columbine shootings. According to the National School Safety and Security Services there have been 116 total deaths in the past 5 years that occurred in schools. Of the 116, 45 have been caused by shootings. Just within the past three months of this new school year, there have been 13 school shooting deaths (fig. 1 and 2). That is an average of nine deaths caused by guns per year for the last five years since Columbine startled society to this devastating problem. The obstacle is in front of all of American to have the incidents of shooting deaths in schools decrease to where they are non-existent. In the state of Colorado, where the world’s media attention was drawn due to Columbine and still is, they have some of the loosest guns laws in the nation. A fact sheet was released by the Violence Policy Center on the same day as the shooting at Columbine High School for some related background information. The press release shows that citizens of Colorado do not have licensing or registration requirements with firearm purchase or possession. There is no waiting period for the purchase of handguns, shotguns, or rifles. There are no age restrictions with the possession of rifles or shotguns, but no person under the age of 18 can have a handgun.

Baby Dumpers in Malaysia Essay

In Malaysia, cabinet decides baby dumping cases investigated as murder or attempted murder to ensure that inhuman acts receive severe punishment (â€Å"Mixed reaction to classifying†, 2010). Some others said that they should given a new chance to repent on what they have done. Our opinions, the punishment is heavy for them due to most of baby dumpers in Malaysia and other countries were committed by underage and teenagers around 20’s. In order to find the solutions for this problem, the community and government need to find the causes and factors that contribute to the problem first. The factors that contribute to baby dumping are cultural values and perspective of the community, HIV/AIDS, poverty and lack of sex education. Cultural value is a concept that a community sharing together about what is right, wrong, possible or impossible, true or false and so on (Young, 2009) while according Oxford dictionary perspective can describe as an attitude or a way of thinking about something. Some of country shares a similar perspective and values. Because of we cripple the issue of baby dumping, so we will focus on what the community thinks that broke into this problem. What makes one girl decided to dump the illegal baby, because they are afraid if they are not accepted by the family and society. This is because having children outside marriage which the mother is no longer involved in a relationship with the father is seen unacceptable in culture in certain country especially in Asian country and Africa (Maundeni & Nnyepi, 2011). Besides that, the mother who carried illegal baby in her belly will think that she would be a shame if people outside the family know about her pregnancy. Due to that, it leads mother to throw or bury their babies (â€Å"Baby-dumping rates soar among school girls†, 2011). Family and community play important roles in this case by giving a moral support for them (Hafidzhi Razali, 2012). Parents and community need to guide them and support them when they go through the phase of their mistake not judging them. This is because they are still young which cannot think what is right and wrong. Yes, they made mistake but the parents and community should correct them and tell them this is not the end of the world. We need to realize that these young people decided to abandon their baby because of they are out of options due to the limitations set upon by social circumstances. From being despised by society and scolded by the family, it is preferable to dump the baby. Abortion is prohibited in all religion no matter you are Christian, Islam, Jews, Buddha or Hindu. Abortion can be like killing a person life so that is why it is prohibits to practice. Many girls who share their experience said that they choose to abandon their babies is because of abortion is prohibited in society (Jia, 2010). Like we mentioned earlier, these girls are young to think what is right to do. So they think that abandon the baby is the best options rather than abortion. This is because they believe that abandon the baby in the dustbin which the baby is still alive is so much better than abort. The second factors that contribute to baby dumping are human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS). When we say about HIV/AIDS, society always has negative thought about the disease. When someone get infected by other people, they will get the punishment too even though it not their fault. A child with HIV/AIDS always get insulted and negative look from the society even though they didn’t ask for the disease. Issue on baby dumping has been widely happen around the world. The baby been dumped because of the infected of HIV/AIDS. HIV/AIDS can be transmitting through sexual contact with the infected, sharing needles or other injection equipment with the infected person, through an open cut or wound and mother to infant. Mother to child transmission of the disease can be happen during the pregnancy month, delivery and after birth and breastfeeding (Otti & Jallow, 2003). This is called perinatal transmission that is usual way the disease transmitted to the child (American Pregnancy Association, 2012). The chances for the baby to be infected is 25% if the mother not taking any treatment during the pregnancy. Baby gets infected by the virus through the blood circulation from the mother HIV-positive, make the fetus to be exposed in the HIV process (Cichocki, 2010). Therefore, the mother who infected will feel depressed due to the transmission of HIV. The depression will lead the mother to dump the baby as her last option. During the delivery, the connection between mother and baby are umbilical cord, which connects the baby with the mother body fluids and blood that contains the virus. The body fluids may get the baby to be infected. Mother with HIV positive are not allow to breastfeed their babies because of the mother milk has very high concentration of HIV. They have been suggested to give commercial milk formula to their babies to avoid the babies from being infected. Due to that, it is kind of burden to the mother to spend money on commercial milk. The other major factor that will contribute to baby dumping is poverty. As we know that if the parents do not have any money to raise the child, they may dump their babies so that they will not have to pay all the baby basic’s requirements, (Sulayman Makalo, n. ). For example, to raise a good baby they will need shelter, and some other basic requirements. For some poor families, they cannot afford for the shelter. This is due to the money shortage and they neither able to buy nor rent a house for the family. Most of the cases of baby dumping are happened in the poor country such as Africa, (Skosana, n. d). There are so many people who live incompetent where some of the families did not plan the pregnancy, but then after the mother pregnant they are not able to raise and give the basic requirements to the baby. This include for the baby’s food, clothes and education. This may affect the developmental growth of the children (Sulayman Makalo, n. d). They dump their baby and hoping that someone will take care for their child with complete requirements with proper education. Other than that, there are some cases that the mother abandoned the baby as a solution due to desperation, (â€Å"Baby dumping-A genocide†, 2012). According to Gosamalang (2011), most of the women who leave and kill their babies are poor, single mother and often the first time mother. This may happen because they are fear of being poor while raising the child. Besides that, there will be a lot of cost needed to grow a child, to buy their food, milk, diapers and clothes. The mother may desperate and under pressure and finally they will dump the baby. Moreover, the father of the child doesn’t want to take the responsibility for the child, which may be the unwanted pregnancy and have no money and disable to grow them. In the developing country such as Malaysia, most of the cases are related to teenagers. This is because eenagers are still young, full with curiosity and not able to raise their own babies, (â€Å"Baby dumping-A genocide†, 2012). They only know to enjoy their youth while they actually have no money and not able to carry a huge responsibility, such as take cares their own baby. They are the largest group who neglect their babies with hope they can start a new life. They also should be studying in school or college where they have no sufficient money to survive with the baby. Here, it can be concluded that poverty is one of the major causes that escalates the baby dumping cases worldwide. The last factors that contribute to baby dumping are sex education. Nowadays, these youngsters are lack of knowledge about sex education, which they are clueless about it. In Nazni Noordin et al, 2012, research; they said that with not enough knowledge on sex, it adds to unwanted pregnancy which it can lead to the baby dumping issues. With the knowledge on sex education, the youngsters can differentiate between bad and good. So in order that all of these youngsters get all the knowledge on sex education, government must play a vital role so that the baby dumping issues are in control. Moreover, in order to decreases the issues, government should introduce sex education in school to combat baby dumping issues (â€Å"Malaysia Considering Sex Education†, 2010). With introducing sex education to school across Malaysia, it can tackle the widespread of baby dumping issues. Even though by bring out the sex education classes have against conservative elements, saying that it will encourage lechery, but with the abandoned of newborns all over the country by young mothers has forced a reconsider. Other than that, according to Singh and Tan, 2010, with sex education, it is creating an accurate understanding of reproductive health among the young, which it was important in reducing baby dumping. It is believe one of the methods that can adopt to raise awareness among schoolchildren especially the youngsters. To success the education, all sectors, includes government, private sector and non-governmental organizations were needed as part of a complete ways to address baby dumping. Furthermore, sex education in school also can create awareness among young generation towards consequences of free sex (Nazni Noordin et al, 2012). Nazni Noordin et al, 2012, also stated that, teenagers nowadays find it much harder to come up with good reasons to say â€Å"no† to sex and to use birth control pills carefully and it shows that there is low awareness among the teenagers towards the sex which its lead to the unwanted pregnancy and consequently, it will lead to baby dumping. Nazni Noordin et al, 2012 cited from Dr. Ismail Thamby, 2010, usually young generation will not think of the result with their behavior. In addition, it is not only government who responsible to control the baby dumping issues. It also must come from the â€Å"root† itself which is the teenagers’ parents or family. As a parent, they need to be fully aware of what their teenagers is taught in school. In order to overcome this situation, parents and family must be open-minded when it came to sex education or sex talk with their children. Moreover, parents should pay more attention and be more supportive to their children so that the young mothers are not afraid of them if they are pregnant outside the marriage (Nazni Noordin et al, 2012). Furthermore, they need to talk to their children about sexuality issues (Mellanby et al, 1995). Other than that, according to Mellanby et al, 1995, all parents should be prepared to answer questions that their children may have. By this it can be sure that the information that the parents provided is complete and accurate and more importantly, it reflects the family’s values. The parents also must control and aware of their children’s outdoor activities in order to prevents unwanted pregnancies which can lead to baby dumping. As the conclusion, this baby dumping issue is hard to control. Before we think about on how to solve this problem, we have to tackle from the root that contributes to baby dumping. Like we have discussed earlier, the factors that contribute to baby dumping are cultural values and perspective of the community, HIV and AIDS, poverty and sex education. Moreover, baby dumping gives so many negative impacts to our society and we have to take several actions in order to reduce the numbers of baby dumping cases.

Commerce Clause & Health Care

The art oblige was further placed in our administration to insure that states couldnt establish righteousnesss or regulations that would halt with trade and economic craft, in allow gave social intercourse the reason to regulate employment with foreign Nations, and among the several States, and with the Indian Tribes. To me, the avocation Clause was once legitimate in the sense that the economic activity was principally trade based and to prevent the big rivalry among states, Congress needed to exhaust the force-out to mold interstate transaction to render conflicts.When creating and establishing the Commerce Clause I believe it could pass water been thought with and further much written in a more distinct and detailed office to accommodate the issues we swallow had. Be character it wasnt stated, U. S. coercive court of meetice ruled Congress to control intrastate commerce as yen as the commerce signifi give the axetly affects commerce involving more than one state, resulting from Gibbons v. Ogden. Sometimes I wonder if its realistic to see Congress forget give birth to the organize of controlling every aspect of our life, until something deal the low-priced Cargon Act comes into affection and keeps me questioning, what will be next.The establishments argue is, under the Commerce Clause that Congress has the power to mandate the inexpensive negociate Act. Their philosophy is that Congress bunghole demand people to buy wellness insurance policy, and if they refuse, indeedce it would be affecting interstate commerce weakening the Acts other developments. Their reasoning is that there ar individuals who currently do not name medical insurance that argon making a remarkable amount of visits to the doctor. In result, leaving hospitals take ining out to insurance companies to recover what they didnt get salaried for treating the non-insured.Consequently, insurance companies will start acme premiums higher and higher whic h will punish those who already carry insurance and those who reach out for insurance where premiums have raised to a layer that it is unaffordable for the average citizen, and then the problem will get worse. The blood line against the Affordable Care Act is that it violates the Commerce clause regarding the fact that Congress has the power to regulate interstate commerce and intrastate commerce as long as the conflict in commerce is among more than one state.Some states, like Virginia, have passed or are in precondition of declaring a law that the Affordable Care Act cant be enforced in their States. In the name on the Reuters website it says, State legislators in Maine, Montana, Nebraska, Oregon, Texas, and Wyoming have introduced bills that establish penalties, including delightfuls and jail time, for every agent seeking to enforce the health guardianship law within their states borders. Congress has the power to do most of which they feel opened of doing and if they can prove a practised enough argument to the Supreme Court that inactivity affects interstate commerce then I think no look what the States arguments are going to be close down down. Regarding tax, the Government argues that if their power under the commerce clause doesnt support the mandate, then they will implement the power of Congress to tax. The mandate was Congresss result to those who decided they werent going to get health insurance, preventing cost teddy.Cost shifting was their answer as to why they can force the individual mandate and its because the failure to purchase insurance has a substantial and deleterious effect on interstate commerce. The Government believes that health care at some localize in life is unavoidable, whether its an emergency or by means of insurance, thats why they have created the individual mandate penalization to quit from premiums rising. The main argument against the mandated tax is that when lobbying for the bill, electric chair Oba ma stated that there would not be a new tax twisting with the individual mandate requiring coverage.But the penalty will be collected through tax filings and the Federal Government says that the fine is in their power to levy. From the Reuters article it says, States say the U. S. Government does not have the authority to charge the fine and point to the discrepancy between Obamas statements and the U. S. Governments arguments. Government regulation in business is everywhere, from advertising, employment and labor, privacy, environmental, and safety and health issues.The ultimate reason there are so many regulations is so that consumers are protected and it helps businesses to thrive at the alike(p) time. What is so interesting about the law is that we have a firm foundation, entirely the law will always be changing because with time there will come a new consideration with no precedent that will cause a controversy like the Affordable Care Act itself. I just hope it doesnt get to the point that the Government abuses its powers given to them by the framers who created our Constitution to resolve conflict, not create it.
