Let X be a continuous random variable with cumulative distribution function given by F(x) = P(X<x).

Define a new random variable U=F(X). Define a new random variable U=F(X)

In a battery or a galvanic cell, the electric potential of the battery is due to a difference of charges between the two cells like in a capacitor? if yes, why we call it electromotive force of a battery (EMF) ?

How do you find tension and friction on an inclined plane given acceleration, two masses and an angle? It's a pulley system, I suppose.
