To solve this problem we will apply the conventions related to the cinematic movement theorem, for which the kinematic equations of linear motion are equally detached. We will use the speed and position equations to determine the general formula according to the given values.
To velocity function we have

Our values are,



Replacing at this equation and solving we have that the equation for the velocity would be,





Therefore the velocity function is 
At the same time for the position function:

Replacing we have that




Therefore the position function is

Answer:
metal B
temperature flow from high region to low . metal B has more temperature than others
You have to have electrons that are in the materials conduction band. Then you apply a voltage across the material.
The answer is A because potential energy is stored up energy which means that it’s not moving
