If you have to apply 40 n of force on a crowbar to lift a rock that weighs 400 n, what is the actual mechanical advantage of the crowbar?

Actual mechanical advantage = (output force) / (input force)

AMA = (400N) / (40N)

AMA = 10

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
