Answer:
The potential energy of the bowling ball will be mgh
Explanation:
Let the mass of bowling ball =m
The height of building on which bowling ball sits=h
So,
The potential energy of the bowling ball =P.E.= mgh
K.E=0.5*mv²
v=square root 2ke/m
v= square root 2*8J/1 kg
v= 4 m/s
The answer is a. endothermic.
In endothermic reaction, as the name suggests, the reactants require energy absorption to form and complete the chemical reaction to form products.
And even if you don't know the answer, you can exclude all other answers by scientific logic and you will be left with the correct answer.
Hope this helps.
