Answer:
Electric current is directly proportional to potential energy and inversely proportional to resistance.
Explanation:
Deposition is geological process of sediments, soil and rocks that are added to land-form or land mass. Wind, ice, water, and gravity transport weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited. Technically Building up layers of sediment.

A wave carries energy from a source to a point some distance away. A wave is reflected by a barrier. The reflected wave moves away from the barrier at an angle that is equal to the angle with which the incoming wave moved towards the barrier. When a wave is slowed down, it refracts—that is, changes direction.
By idea gas equation we can say

here P = pressure
V = volume
n = number of moles
R = Avagadro gas constant
T = temperature
So from above expression we can see that for constant number of moles we can say




So finally the pressure will be 279.1 kPa
Answer:
It's from crude oil which is black and costly to obtain
