The gravitational force between two objects is represented by the variable F. If the distance is decreased by 5 what is the new

Anvisha [2.4K]

The universal law of gravitation states that:

Every object in the universe attracts every other object with a force which is proportional to the product of their masses and inversely proportional to the square of distance between them.

It means that if the gravitational force is F, then if the distance is decreased by 5 times, then the new gravitation force is:

F/5² = F/25

44. ( John weighs 80 kg, and eats a 1,000 J candy bar. If his

Darina [25.2K]

John can run with the velocity of 5 m/s

Explanation:

Kinetic energy is defined as the energy is being used to do an activity, basically energy associated with the motion of objects in the universe.
The formula used to find the kinetic energy of an object is k = $\frac{1}{2} mv^{2}$ where as k represented as kinetic energy, m is the mass of the object and v is the velocity of the given object.

Here, to find the answer we have to re-write the equation as $v = \sqrt[2]{\frac{2 k}{m} }$
Given, the mass of the object, here it is John = 80 kg, energy needs to be converted to kinetic energy, k = 1000 J.
Hence, substitute all the values, then you would velocity as 5 m/s
