<u>We call changes between solid liquid and gaseous forms of a substance as phase change or change of state.</u>
<u>Explanation:</u>
To change a substance from one state to another, extreme temperatures or pressures are required. Sometimes when a substance doesn't change states we should use all the ideas when that happens. To create a solid, we should decrease the temperature by a huge amount and then add pressure. For example, oxygen will solidify at -361.8 degrees Fahrenheit at standard pressure. However, it will freeze at warmer temperatures when the pressure is increased.
Phase changes happen when a substance reach some special points. Sometimes when a liquid becomes a solid a freezing point or melting point is used to measure the temperature at which a liquid changes into a solid. Some of the phase changes are: Condensation, Freezing, Melting.
Kinetic energy = 1/2 mv^2
1/2 x 50 x 2.6^2
= 169J
This experiment help us understand their behavior as well as how the people will cop up with the rules and regulation the society wants to apply on them
<h3>What is Stanford prison experiment ?</h3>
In a two-week simulation of a prison setting, the Stanford prison experiment was meant to look at the impact of situational factors on participants' responses and behaviors.
Hence, this experiment allows us to better understand their behavior, as well as how individuals will respond to the laws and regulations imposed by society.

Answer:
The average current is 19.567 A
Solution:
As per the question:
Charge, Q = ![8.0\times 10^{- 4}\ C](https://tex.z-dn.net/?f=8.0%5Ctimes%2010%5E%7B-%204%7D%5C%20C)
Time, t = ![35\times 10^{- 6}\ s](https://tex.z-dn.net/?f=35%5Ctimes%2010%5E%7B-%206%7D%5C%20s)
Now,
We know that current is constituted by the rate of transfer of the charge per unit time. Thus we can write:
I =
(1)
Now, the charge that was transferred is 86 % of the original value.
Therefore,
We replace Q by 0.86Q in eqn (1):
I = ![\frac{0.86\times 8.0\times 10^{- 4}}{35\times 10^{- 6}} = 19.657\ A](https://tex.z-dn.net/?f=%5Cfrac%7B0.86%5Ctimes%208.0%5Ctimes%2010%5E%7B-%204%7D%7D%7B35%5Ctimes%2010%5E%7B-%206%7D%7D%20%3D%2019.657%5C%20A)
The gravitational potential energy of an object depends on three things. Its mass, its height above the surface of the earth and the pull of gravity (which is assumed to always be 9.8 m/s².
The Formula for finding the GPE is : m x g x h where m = mass, g = gravitational acceleration and h is height from earth's surface.
Using this formula we can find that :
GPE= 75 x 9.8 x 300 = 220500J (where J is the SI unit for GPE and stands for Joules.
