Based on the data collected, the substance that would have the highest temperature change when absorbing an equal amount of heat energy would be one kilogram of a. copper. b. iron. c. aluminum. d. water.

frequency or wavelenth of em radiation in a vacuum

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

e/c, where e is its total energy
