Plan a controlled experiment to investigate how an object’s position is related to the amount of its potential energy by measuring how high the ball bounces. Choose at least four heights from which you will drop the ball. The drop heights may be increased or decreased based on the bounciness of ball. Describe your experiment.

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
