Answer 1

both A & B

Answer 2

Use the following formula to calculate mechanical advantage. To lift a load, you apply 40.0 N of force to a lever. The lever applies 180 N of force to the load. What is the mechanical advantage of the lever?

4.5
15.0
6.2

Answer 3

To calculate mechanical advantage, you use the formula:

Mechanical Advantage = Load Force (output force) / Effort Force (input force)

In this case:
Load Force = 180 N
Effort Force = 40.0 N

Mechanical Advantage = 180 N / 40.0 N
Mechanical Advantage = 4.5

Therefore, the mechanical advantage of the lever is 4.5.
