Compare the patterns of field lines in each gravitational field model. What can you conclude about the strength of the field models? Choose all that apply. A) The strength of the gravitational field is the same at the surface of the Sun, Earth, and the moon.
B) The strength of the sun's gravitational field decreases as the distance from the sun increases.
C) The gravitational field at Earth's surface is greater than the gravitational field at the moon's surface. ​

This problem has been solved! see the answera non-uniform fire escape ladder is 6.0m long whenextended to the icy alley below. it is held at the top by africtionless pivot, and there is neglibible frictional force fromthe icy surface at the bottom. the ladder weighs 250n, and it'scenter of gravity is 2.0m along the ladder from the bottom. amother and child of total weight 750n are on the ladder 1.5m fromthe pivot. the ladder makes an angle θ with the horizontal.find the magnitude and direction ofa) the force exerted by the icy alley on the ladderb) the force exerted by the ladder on the pivotc) do your answers in part a and b depend on the angle?
