Fill in the bianks to show how nuclear energy changes into electrical energy inside a nuclear power plant

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.

option number c is the right answer.

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
