The answer is definitely letter C. They are both located in the nucleus. Their summation define the mass of one (1) atomic mass unit of a particular element. For example, for carbon atom it has 6 protons and 6 neutrons. Therefore the atomic mass of carbon is 12.
Answer:
A. increase the speed
Explanation:
For you to be able to shorten the time it takes for the care to get to its destination, you must increase the speed because if the distance is the same that means you have to increase your speed.
Answer:
The magnitude of change in momentum of the ball is
and impulse is also
Explanation:
Given:
Velocity of a pitched ball

Velocity of ball after impact

From the formula of change in momentum,

Here mass is not given in question,
Mass of ball is 
Change in momentum is given by,


Magnitude of change in momentum is

And impulse is given by


So impulse and
Therefore, the magnitude of change in momentum of the ball is
and impulse is also
I think it is high pressure / gravity and high temperatures
The answer would be a nail rusting, but really it could be any of these.
