Right, as you mentioned in the comments, you find 
by plugging in the different values of 
.
For 
, we have
Similarly, for 
, you get
An example of something that is not a proton would be an electron. It has a negative charge and has a charge of 1.6X10^-19 Coulombs.
One is bigger than the other and they are the same shape
In order to calculate the amount of energy required, we must first check the latent heat of vaporization of water from literature. The latent heat of vaporization of any substance is the amount of energy required per unit mass to convert that substance from a solid to a liquid. For water this is 2,260 J/g. We now use the formula:
Energy = mass * latent heat
Q = 50 * 2,260
Q = 113,000 J
113,000 Joules of heat energy are required.
Answer:
300 Pascal
Explanation:
Given
weight or force (F) = 6000 N
area (A) = 20 m²
pressure (p) = ?
we know
the force acting normally per unit area is pressure. So
P = F / A
= 6000 / 20
= 300 Pascal
Hope it will help :)
