The table provided shows data collected during an experiment . Which of the following claims is supported by the data?

A. Gravitational force are proportional to the masses of the two objects.

B. Gravitational forces are strongest between objects with identical masses.

C. Gravitational forces are weakest when one object is more massive than the other.

A. Gravitational force are proportional to the masses of the two objects.

Explanation: the table shows during an experiment

given data:

determine the horse power (h.p) = ?

force applied to move the box(f) = 10 pounds,

box lifted from a distance         (d) = 3 feet

time taken to lift                         (t) = 10 sec,

the horse power is defined as amount of work required to move a load. the horse power is equal to 550 foot-pound per second

                  1 h.p   = 550 foot-pound/second

it can also be defined as the the load that need to be move a body for certain distance in a certain amount of time.

mathematically,

                      h.p = (force × distance)/ time

                            = (10 × 3)/ 10

                            = 30/10

                            = 3 foot -pound/sec

hence, the horse power is needed to move the box is 3 foot-pound/second

important note: 1 h.p = 550 foot-pound/second = 746 watts

it is the second option.
