A car is raised a certain distance in a service station lift and therefore has potential energy relative to the floor. If it were raised twice as high, how much potential energy would it have relative to the floor?

Explanation:

In this case, the potential energy is the energy that a body (m) possesses by virtue of its height (h) above the earth's surface, is defined as:

Where g is the gravitational acceleration. We have , so:

i think the answer is b

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.
