Which of the following free body diagrams best represents the gravitational pull in the Sun-Earth system? (relative size of Earth, blue circle, and Sun, yellow circle, not drawn to scale). A B C There is no gravitational pull between Earth and the Sun. Briefly explain your answer to the previous question.

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....

Since Moon is attracted to Earth, why doesn't it fall onto Earth? because it has large tangential velocity because there is another equal force on the Moon that balances gravity because centrifugal force balances gravity because centrifugal force more than balances gravity because it has too much inertia to fall towards Earth A. Ocean tides occur mainly because water always runs to the low spot water always runs to the side of the Earth away from the Moon B. water...

The moon does not fall to earth because: The moon is beyond the main pull of Earth's gravity. The moon is pulled by the sun and planets as well as by Earth. The gravitational force provides the required centripetal force for the moon to have its tangential speed around the Earth. The net force on the moon is zero. The moon is in earth's gravitational field. Question 3 (4 points) The tallest mountain in our solar system is Mt. Caloris...

Warm Up The surface of the Earth receives approximately 1000 W/m2 (Watts per square meter) of energy from the Sun. This number rises to about 1386 W/m2 in the upper atmosphere (r 6.4 x 106 m) The sun is 1 AU (1.496 x 1011 m) away Over what area is the Sun's energy spread at the Earth's distance? How much power is the Sun releasing?

The intensity of radiation reaching the earth from the sun is 1350 W/m2. The earth's radius is 6.4 ´ 106 m. How big a force does this radiation exert on the earth? (Assume it is all absorbed.)

Because the earth's orbit is slightly elliptical, the earth actually gets closer to the sun during part of the year. When the earth is closer to the sun its orbital speed is greater than when the earth is farthest away from the sun. less than when the earth is farthest away from the sun. the same as when the earth is farthest away from the sun.
