9 The force F keeping the moon in its orbit round the earth is inversely proportional to
the square of the distance r from the earth.
If F = 6 x 105 KN, and r = 8 x 108 m,
Find: 1
(a) the equation connecting F and r
(b) ) the value of F when r = 16 x 108 m
(c)
the value of r when F= 24 x 109 KN.

where in your body is there an enzyme that does function at a high or low ph? what is the name of that enzyme and its function?

idk let me see fdfdgdg

the answer is c because it is most logical.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
