What is the value of the gravitational acceleration at the surface of the Sun relative to...
A planet has a gravitational acceleration on its surface of 0.5 times Earth's gravitational acceleration on its surface. The planet's radius is two times Earth's radius. What is the mass of the planet, in terms of Earth masses, ME? Hint: Write equations for the gravitational acceleration on the surface of the planet and on Earth's surface in terms of their respective masses and radii. Then write the relationships between Earth's and the planet's gravitational accelerations, and between the Earth's and...

Case #3: What is the gravitational acceleration due to the Sun at a distance of 40 AU (Where Pluto's located)..
2. Consider a system consisting of the Sun, Earth, and a satellite in a circular orbit about the Earth. (a) Plot the gravitational acceleration of the satellite due to Earth's gravity as a function of the altitude of the satellite as measured from the surface of the Earth. Scale your plot so that the altitude goes from 0 km to 104 km. (b) Assume that the satellite instantaneously lies on the line between the Earth and the Sun. Make two...
A The Earth exerts a gravitational pull of 2.0 ×1020 N on the Moon; the Sun exerts a gravitational pull of 4.3 ×1020 N on the Moon.What is the net force on the Moon when the angular separation between the Earth and the Sun is 90 as seen from the Moon? B : A gun on the shore (at sea level) fires a shot at a ship which is heading directly toward the gun at a speed of 40 km/h....
