Shelia eats an energy bar right before she goes on a run. what energy changes will occur in shelia as she runs after eating

The chemical energy in food is converted to potential energy stored in the body which is then converted to mechanical and kinetic energy, as a result of motion while running then to heat energy.

Explanation:

The chemical energy in nourishment is changed over to potential energy stored in the body which is then changed over to mechanical and kinetic energy, because of movement while running then to heat energy.   The energy bar eaten by Sheila has chemical energy bolted up inside it. This chemical energy is changed over to mechanical energy in a type of potential and kinetic energy and this is changed over to heat energy as the run progresses. Along these lines, the energy changes are chemical energy to mechanical energy [kinetic and potential] and finally to heat energy.

Yes

Step-by-step explanation:

Think of x as apples

You have 7 apples and 5 apples you can mix them together and you have 12 apples and you would not be able to sort them apart

7x+5y are not like terms

You have 7 apples and 5 grapes.  You can easily tell them apart.
