What is potential energy?
a) the energy of change
b) the energy of position or composition
c) the energy of mass or volume
d) the energy of motion

B.) the energy of position or composition

Explanation:

Potential energy is the energy possessed by a body by virtue of its position or composition relative to others, stresses within itself, electric charge, and other factors.

The correct answer is B)the energy of position or composition

Explanation:

Potential energy is defined as that capacity that a given body has to perform a job according to its position. Example: a spring, when compressed or stretched (it is elastic potential energy).

it is the most commonly accepted one

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
