Momentum
<h2>
Explanation:
</h2>
The momentum of a particle is defined as the product of the particle mass and the particle velocity as follows:
On the other hand, the impulse of a constant force is defined as:
We also know that the net force acting on a particle equals the rate of change of the particle’s momentum, so:
If the force is constant, then 
equals the total change in momentum over a period of time:
Well, it is not ultraviolet rays and I highly doubt it is visible light. I would say gamma rays. Hope this helps! :)
ANSWER B: A location can only have one elevation.
Answer:
an instrument for measuring an electromotive force by balancing it against the potential difference produced by passing a known current through a known variable resistance.
In order to change the frictional force between two solid surfaces, it can be changed by shorter distances and by the amount of weight it has or the amount of force that is pushing that object to go however distance it can.
