Answer:
Explanation:
Power is defined as the energy produced (E) per unit of time (t):
This means that the energy produced in the Sun each second (1 s), given the power , is
Each p-p chain reaction produces an amount of energy of
in order to get the total number of p-p chain reactions per second, we need to divide the total energy produced per second by the energy produced by each reaction:
