The diagram below shows the force exerted on object m1 due to the gravitational attraction between m1 and m2. what is true about the force exerted on m2 due to the gravitational attraction between m1 and m2?
a. it is directed to the right.
b. it is directed to the left.
c. it is directed upward.
d. it is directed downward.

B. It is directed to the left.

Explanation:

Gravitational force is an attractive force, this is stated by Newton's law of Gravitation:

"The force exerted between two bodies of masses m1 and m2 and separated by a distance  is equal to the product of their masses and inversely proportional to the square of the distance"

This means both m1 and m2 are mutually attracted.

Hence, if the force exerted on m1 by m2 is directed to the right, the force exerted on m2 by m1 must be logically directed to the left.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

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.
