The table shows dimensions of four wheel and axles. which shows the order of mechanical advantage from least to greatest? a- y, x, w, z b- z, w, x, y c- z, x, w, y d- y, z, w, xanswe is b

Mechanical advantage is given by formula

here we know that for torque balance in pulley system we have

for W

for X

For Y

For Z

so least to greatest order will be

Z < W < X < Y

so correct answer is

B- Z, W, X, Y

the answer is a. at the equator

frequency or wavelenth of em radiation in a vacuum
