A falling apple is an example of which type of energy? Select all that may apply. A. kinetic energy
B. potential energy
C. chemical energy
D. atomic energy
E. gravitational energy

(Multiple choice)

A.kinetic energy

Explanation:

When an apple falls from the tree to the ground, its energy of position (stored as gravitational potential energy) is converted to kinetic energy, the energy of motion, as it falls. When the apple hits the ground, kinetic energy is transformed into heat energy.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
