- The International Space Station (ISS) orbits Earth in a nearly circular orbit that is 345 km above Earth's surface. 1) How many hours does it take for the ISS to make each orbit? (Express your answer to three significant figures.) 2) Some of the experiments performed by astronauts in the ISS involve the effects of "weightlessness" on objects. What gravitational force does Earth exert on a 12.0-kg object in the ISS? Express your answer in newtons. (Express your answer to three significant figures.) 3) What gravitational force does Earth exert on a 12.0-kg object in the ISS? Express your answer as a fraction of the force that Earth would exert on the object at Earth's surface. (Express your answer to three significant figures.)1.) In what way(s) is Einstein's general theory of relativity superior to Newton's theory of universal gravitation? For each way, give an example of a case where Einstein's theory provides a more accurate description of physical phenomena than does Newton's. (Select all that apply.) A.) Newton's theory originally held that the orbit of a spherical object about another will be an open curve for which the point of closest approach slowly precesses. Einstein's theory correctly predicts that gravitational forces lead to orbits of closed ellipses. B.) Einstein's theory correctly predicts the deflection of light passing near a massive object, while Newton's theory predicts a deflection that is one-half the observed deflection. C.)

- Astrology, that unlikely and pseudoscience, makes much of the of the at the The force that a planet could exerts gravitational, if there is anything to astrology we should expect this force to be significant Part A: calculated the gravitational force, in newtons , exerted on a 3.8 kg baby by a 105 kg father who is distance of 0.18 m away at the of its birth? Part b: Calculate the force on the baby, in newtonsdue to Jupiter (the largest planet, which has a mass of 1.90*10^ 27 kg) if it is at closest distance to Earth, 6.29 * 10 ^ 11 m away Part c: what is the ratio of the force of the father on the baby to the force of Jupiter on the babyAnswer the two questions below and write the solution. a. An astronaut is tasked to compute the gravitational acceleration of planet Z. After landing, he dropped a test object from a height of 2 meters and the time duration of the drop was 1 second. What is the gravity of planet Z in m/s^2? b. If the astronaut jumped upward with an initial velocity of 8m/s, how high is the jump? in metersThe gravity on Mars is about 38% that of Earth's gravity. Let's say some cargo has a mass of 15 kg here on Earth. First, what would be the weight of that cargo in kilograms on Mars? Explain your answer. Second, what would be the mass of that cargo in kilograms on Mars? Explain your answer.
- 1. using Newton’s Law of Universal Gravitation and some kinematics calculation we can calculate the mass of the planet. For this, use this equation below: ?planet =(9.340×1024)×(vmax)×(Pstar)1/3×(Mstar)2/3 Given: - vmax = 1.5 m/s - Pstar = 3.5 days - Mstar = 1.148 Msun, where Msun = 1.98847×1030 kg. This calculation is not shown.Newton's Law of Gravity is what can we say about the law, and about G? Check the 4 correct statements. There will be partial credit if you miss some. We must find G by making precision experimental measurements because we do not know its value otherwise. All evidence suggests that It is the same everywhere, for all time Its value sets the "size" or "strength" of gravitational force We can calculate G from first principles and understand why it has the value it does. This law of gravity only works near Earth. In space far from Earth there is no gravity. It may not apply very close to very large masses where General Relativity takes over as a better description.1. Compare the gravitational attraction between objects on earth and interaction of celestial bodies in space. Which gravitational force is almost negliable? Why? 2. Discuss why the study of a gravitational field is important.
- 1. Is it accurate to say that astronauts in the International Space Station orbiting the Earth, are able to float and bounce around the station because they are in zero gravity? Why or why not? 2. If I stand a certain distance from an object, and our gravitational force is some unknown value F, how will that value change if I go twice as far away from the object as I started? Will the gravitational force now be twice as strong, half as strong, or something else? Explain your answer.Please answer the question and subquestions entirely. This is one single question. According to the official guideline, I can ask two subquestions! Thank you! 1) The radius of Planet Z is 3 times the radius of the Earth. It has the same density as the Earth. What is the gravitational acceleration at the surface of the planet? 29 m/s2 88 m/s2 270 m/s2 3.3 m/s2 a) Use Kepler's Law to find the time (in Earth’s years) for Mars to orbit the Sun if the radius of Mars’ orbit is 1.5 times the radius of Earth's orbit. 1.8 2.8 3.4 4.2 b) The mass of Mars is about 1/10 the mass of Earth. Its diameter is about 1/2 the diameter of Earth. What is the gravitational acceleration at the surface of Mars? 9.8 m/s2 2.0 m/s2 3.9 m/s2 4.9 m/s2 none of theseAs discussed in class, the moon is receding from the Earth due to tides at a rate of ~4 cm/year. Let’s assume that rate has been constant throughout time (it wasn’t, but we can use it to illustrate some key points). Its current semi-major axis is 384,400 km.a) If the moon formed 4.5 billion years ago and has been receding from the Earth ever since, what was its original semi-major axis? What was its original orbital period?b) What would the apparent size of the Moon have been in the sky as viewed from Earth? That is, in Hmwk 2, you were told the diameter of the Moon spans about 0.5o when viewed from Earth today. What would it have been when the Moon first formed?
