Chris is studying the theories of newton and einstein. which theory explains why gravity between two objects changes when the distance between them changes? einstein's theory because he suggested that the more distance there is between objects, the more space-time curves and the greater the strength of gravity is einstein's theory because he suggested that the more distance there is between objects, the more space-time curves and the weaker the strength of gravity is newton's theory because he suggested that the greater the distance between objects, the greater the pull of gravity newton's theory because he suggested that the greater the distance between objects, the weaker the pull of gravity

Newton's theory because he suggested that the greater the distance between objects, the weaker the pull of gravity.

Explanation:

According to Newton's law of gravitation:

Newton suggested that there exists a force of attraction between any bodies having mass which is directly proportional to their masses and inversely proportional to the square of the distance between them.

This means, with increase in the distance between two bodies, the gravitational force between them decreases. Gravitational force is the weakest force in nature.

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
