At what height would the gravitational potential energy have a value of 73.7 joules for a 15 kilogram object? note that acceleration due to gravity is 9.8 meters/second2.. a. 0.5 meters. b. 1.2 meters. c. 2.0 meters. d. 3.1 meters. e. 3.4 meters

Option A is correct

0.5 m

Step-by-step explanation:

Potential energy(P.E.) is given by:

               ....[1]

where,

m is the mass

g is the acceleration due to gravity

h is the height.

As per the statement:

Potential energy have a value of 73.7 joules for a 15 kilogram object.

⇒ and m = 15 kg

Use: g = 9.8 m/s^2

Substitute these in [1] we have;

⇒

Divide both sides by 147 we get;

⇒ m

Therefore,  height would the gravitational potential energy have a value of 73.7 joules for a 15 kilogram object is, 0.5 m

d 192

step-by-step explanation:

we find our area to find area we multiply thoses numbers to get our answer so our area is 192

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
