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

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h
