Answer:
it is below pls give 5 star
Explanation:
Foods contain stored potential energy in the form of chemical energy. When we consume food, the particles undergo a chemical reaction that releases the chemical energy. In turn, this energy is used by the body to perform its daily activities.
Therefore, when you eat a bowl of vegetable soup, you get the chemical energy that is stored in it.

It attracts two charged particles which are separated by a definitive distance.......
The total mechanical energy of the ball is the sum of its potential energy U and its kinetic energy K, therefore:
so, the total mechanical energy of the basketball is 118 J.
