Static friction is what you are looking for.
Kinetic friction is the force exerted on an already moving object, slowing it down.
Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.
thats what i got when i looked it up
Answer:
61.105 C
Explanation:
Charge: This can be defined as the product of current flowing through a circuit and time. The S.I unit of charge is coulomb's (C)
I = Q/t ................. Equation 1
Where I = current, Q = Charge, t = time.
Note: The current through a cross sectional area of the compressor is the amount of charge passing through the area per unit time.
Q = It ............... Equation 2
Given: I = 121 A, t = 0.505 A.
Substitute into equation 2
Q = 121(0.505)
Q = 61.105 C.
Hence the charge passing through the cross sectional area of the circuit = 61.105 C
