You have to have electrons that are in the materials conduction band. Then you apply a voltage across the material.
Answer:
Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. Usually, this process uses oxygen, and is called aerobic respiration. It has four stages known as glycolysis, Link reaction, the Krebs cycle, and the electron transport chain
hope this helps
have a good day :)
Explanation:
Answer:
<em>PE = Fd</em>
Explanation:
Potential energy is the energy possessed by a body by virtue of its position. It is expressed mathematically as:
PE = mgd
m is the mass
g is the acceleration due to gravity
d is the distance
Since Force F is expressed as the product of mass and acceleration due to gravity then, F = mg
Substitute into the formula above:
Recall that: PE = mgd
Since F = mg
PE = Fd
<em>Hence the required expression is PE = Fd</em>
