A4.02 × 10−5 kg raindrop falls vertically at constant speed under the influence of gravity and air resistance. after the drop has fallen 43 m, what is the work done by gravity? the acceleration of gravity is 9.8 m/s 2

Suppose while hauling rocks, you accidentally drop one. it breaks apart in flat, planar sections. what type of rock did you just drop? 20 points

Which statement is true? a) the work done to lift an object 6 meters is greater than the gravitational potential energy it gains. b) the work required to push an object is less than the work required to pull an object the same distance. c) the work required to raise an object to a height is equal to the gravitational potential energy the object gains. d) the work done against gravity to lift an object straight up is greater than the work required to roll it up a ramp.
