3 the velocity by which object m
hits the earth is *

(GM/R)^0.5
1/2× (GMm/R)
- GMm/3R
4/3 × (GM/R)
(4/3 × GM/R)^0.5

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

increase masses, decrease separation

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

the inner core.

good luck: )
