A skydiver jumps out of an airplane at 10,000 feet above ground (Position A). Then continues falling until he opens his parachutes and lands safely on the ground. Question:
A. Given the positions above (Position A and Position B), at which position does the skydiver have the higher potential energy? Explain. (1 point)

B. Given the position above (Position A and Position B), at which position does the skydiver have the higher kinetic energy? Explain. (1 point)

Which best describes the difference between internal and thermal energy?

0.5 kg of silver increases temperature from 0 celsius to 7 celsius when heat is added how much heat energy produced this change in temperature

Your physics assignment is to figure out a way to use electricity to launch a small 6.0-cm-long plastic drink stirrer. you decide that you'll charge the little plastic rod by rubbing it with fur, then hold it near a long, charged wire, as shown in figure p23.56 . when you let go, the electric force of the wire on the plastic rod will shoot it away. suppose you can uniformly charge the plastic stirrer to 10 nc and that the linear charge density of the long wire is 1.0 x10-7 c/m. what is the net electric force on the plastic stirrer if the end closest to the wire is 2.0 cm away?
