Answer:
Increases.
Explanation:
The electric potential increases when the two positive charges of same magnitude bring close to one charge to another because there is repulsive force between them due to same charge and when the two opposite charges move away from each other, the potential energy decreases. When two opposite charges are brought closer together, electric potential energy decreases while on the other hand, when we move opposite charges apart from each other than the work done against the attractive force that leads to an increase in electric potential energy.
1) <span>The function of the electron transport chain is to pump protons in the mitochondrion inter-membrane, thus building up a proton gradient. This gradient will allow the ATP syntheses</span><span>.</span>
2) Why we need oxygen for the electron transport chain:
At the end of the electron transport chain is the Oxygen that will accept
electrons and picks up protons to form water. If the oxygen molecule is not there the electron transport chain
will stop running, and ATP will no longer be produced. Basically, we need the oxygen to produce more ATP.
Answer:
The displacement of the air drop after 3 second is 18.27 m.
Explanation:
Mass of the rain drop = m = 
Weight of the rain drop = W
Duration of time = t = 3 seconds

Drag force on rain drop = 

Motion of the rain drop:

Net force on the rain drop , F= W - D




v = 12.18 m/s
Initial velocity of the rain drop = u = 0 (since, it is starting from rest)
v=u+at (First equation of motion)


(second equation of motion)

s = 18.27 m
The displacement of the air drop after 3 second is 18.27 m.
Answer:
a)COP = 1.67
b) W = 300 J
Explanation:
given,
refrigerator removes = 500 J from a cold reservoir
discharge = 800 J to its hot reservoir
a) COP =
COP =
COP = 1.67
b) heat per cycle exhausted to the
W + 500 = 800
W = 800- 500
W = 300 J
