Melissa and David were playing on the tire swing that hangs from the big oak tree in their yard. While Melissa was sitting in th

e tire hole, David pulled the tire to the side and over his head with his hands and sprinted as fast as he could. His efforts allowed Melissa to swing really high. Beginning with Melissa sitting in the tire swing above David's head, list and explain the energy conversion taking place as she moves.

I think the energy conservation that is taking place is the force between two unbalanced forces pushing and pulling on the tire with the extra force added when David pushed Melissa in the tire... Hope this helps ^-^

Answer:

9.3\cdot 10^{37}

Explanation:

Power is defined as the energy produced (E) per unit of time (t):

P= \frac{E}{t}

This means that the energy produced in the Sun each second (1 s), given the power P=4.0\cdot 10^{26}W, is

E=Pt=(4.0\cdot 10^{26}W)(1s )=4.0\cdot 10^{26} J

Each p-p chain reaction produces an amount of energy of

E_1 = 4.3\cdot 10^{-12} J

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:

n=\frac{E}{E_1}=\frac{4.0\cdot 10^{26} J}{4.3\cdot 10^{-12} J}=9.3\cdot 10^{37}
