Arelationship exists between gravity, mass, and distance. the greater the mass of the objects, the greater the gravitational force between them. the greater the distance between the objects, the weaker the gravitational force between them. which of these objects would have the greatest gravitational force between them? two objects, each with a mass of 10 kg, separated by a distance of 10 m two objects, each with a mass of 20 kg, separated by a distance of 10 m two objects, each with a mass of 20 kg, separated by a distance of 15 m two objects, each with a mass of 10 kg, separated by a distance of 15 m

The gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the distance between the two objects. hence the Gravitational force is given as

F = k (product of masses)/(distance)²                      where k = constant

when mass of each object = 10 kg , distance = 10 m

F = k (10 x 10)/(10)² = k

when mass of each object = 20 kg , distance = 10 m

F = k (20 x 20)/(10)² = k (400/100) = 4k

when mass of each object = 20 kg , distance = 15 m

F = k (20 x 20)/(15)² = (1.8) k

when mass of each object = 10 kg , distance = 15 m

F = k (10 x 10)/(15)² = (0.44) k

hence the force is greatest when

two objects, each with a mass of 20 kg, separated by a distance of 10 m

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
