Why are negative charges more mobile than positive charges?

This is because the protons have more mass and are harder to get moving. Although electrons are very small, their negative electrical charges are still quite strong. Remember, the negative charge of an electron is the same as the positive electrical charge of the much larger in size proton.~Tori

Explanation:

A) 100

B) 10

C) 0.01

Explanation:

Let

Fs = force on slave cylinder

Fm = force on master cylinder

Given that the designed to exert a force 100 times as large as the one put into it. That is

Fs = 100 Fm

Using Pascal's law

Fs/As = Fm/Am

100Fm/As = Fm/Am

100/As = 1/Am

Cross multiply

As= 100Am

As/Am = 100

b) What must be the ratio of their diameters

Using their areas ratio, area of a cylinder is  πr^2

A = πr^2 =  π(D/2)^2

 π(Ds/2)^2 ÷  π(Dm/2)^2 = 100

(Ds/2)^2 ÷ (Dm/2)^2 = 100

(Ds/Dm)^2 = 100

Ds/Dm = 10

(c) By what factor is the distance through which the output force moves reduced relative to the distance through which the input force moves? Assume no losses to friction

Let us consider the workdone at the input and at the output.

Work done = force × distance

Fs × Hs = Fm × Hm

100Fm × Hs = Fm × Hm

100Hs = Hm

100Hs/Hm = 1

Hs/Hm = 1/100

Hs/Hm = 0.01
