Which of the following correctly compares gravitational force and distance between two objects?

as the distance increases, the gravitational force increases.
as the distance increases, the gravitational force decreases.
as the distance decreases, the gravitational force decreases.
there is no relationship between gravitational force and distance between two objects.

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
