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

The energy changes that occur is the energy bar is converted to chemical energy in her body from that it will be stored as a potential energy which will be expressed as kinetic energy she uses in running

Explanation:

As sheila eats the energy bar it supplies her body energy. However, this energy must be converted from the energy bar into an energy source that the body can use. The process of getting energy from the energy bar is called cellular respiration.

What is Cellular Respiration?

the food we eat provide energy When we need a quick boost of energy, we might reach for an apple or an energy bar like sheila. these foods are broken down so that cells can use them. Through the process of cellular respiration, the energy in food is changed into energy that can be used by the body's cells.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
