- During a solar eclipse, the Moon is positioned directly between Earth and the Sun. The masses of the Sun, Earth, and the Moon are 1.99 x 1030 kg, 5.98 × 1024 kg, and 7.36 x 1022 kg, respectively. The Moon's mean distance from Earth is 3.84 × 10 m, and Earth's mean distance from the Sun is 1.50 × 10'" is G = 6.67 x 10-1' N•m²/kg². m. The gravitational constant Find the magnitude F of the net gravitational force acting on the Moon during the solar eclipse due to both Earth and the Sun. 2.6 x1045 F = N IncorrectCalculate the acceleration due to gravity on the Moon. The Moon's radius is 1.74 × 106 m and its mass is 7.35 × 10²2 kg.Two 3.8 kg physical science textbooks on a bookshelf are 0.25 m apart. What is the magnitude of the gravitational attraction between the books?
- Two books are on a shelf 1.3 m from one another. Book A has a mass of 2.2 kg. Book B hasa mass of 1.7 kg. An absentminded student picks up book A to see if it is useful for his re-search paper. He decides not to use the book and sets it on a shelf 1.8 m from book B.What effect does this have on the gravitational force between the books?AThe gravitational force remains the same because the masses of the books remainconstant.BThe gravitational force decreases because the distance between the books increases.The gravitational force increases because the distance between the books increases.DThe gravitational force remains the same because distance does not affect gravity for small objectsTwo objects of equal mass are located at 1.0m and 2.0m above the surface of the Earth. Explain why we can treat the gravitational force on these objects as being equal, even though they are different distances from the center of the Earth.One of your summer lunar space camp activities is to launch a 1210-kg rocket from the surface of the Moon. You are a serious space camper and you launch a serious rocket: it reaches an altitude of 229 km. What gain in gravitational potential energy does the launch accomplish? The mass and radius of the Moon are 7.36 × 1022 kg and 1740 km, respectively.
