<span> A reaction in which energy is absorbed from the surroundings is called an endothermic reaction. In endothermic reactions the enthalpy of the products is greater than the enthalpy of the reactants. Exothermic reactions heat up their surroundings while endothermic reactions cool them down.
I hope this helps you </span>
When the elevator is going up (assuming the elevator is acceleration)
When the elevator is accelerating downwards, the total gravitational force would be larger.
If the elevator is accelerating upwards, then the gravitation force would be smaller, thus the tension in the string would be smaller.
It means that the car has covered
(35 miles) x (the number of hours since it started traveling).
At some points during that time, the car was most likely moving
faster or slower than 35 miles per hour. We don't know. We only
know that it covered (35 miles) x (the number of hours since it left).
To solve this problem we will start by applying the given load ratio, and we will rely on the two types of distances given. Later we will use Gauss's law and through its integrals, in which it is equivalent to the potential we will obtain its value in the center of the sphere. Since it is uniformly charged we have to,
By Gauss Law
Here, E is the electric Field and is equal to
For 
being the Permeability constant at free space
Replacing with the previous value we have,
Then the value of the electric field is,
Now potential
