How can we mathematically express Newton's law of gravity? (In the following, F is the force of Gravity, G is a constant; m and M are the masses or two bodies (such as the Earth and the Sun); and r is the distance between the centers of mass of the two bodies.)

Step-by-step explanation:

Force of gravitational attraction, Fg = GMm/r^2

Where,

G = gravitational constant

M = mass of object 1

m = mass of object 2

r = distance between the point masses.

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.
