The mass of the moon is 7.36×1022kg and its distance to the earth is 3.84×108m. what is the gravitational force of the moon on the earth?

The gravitational force is F =  

Explanation:

To answer this question we need to recall Newton's Universal Law of Gravitation for the force "F" exerted from one object to the other:

where G is the Universal gravitational constant =

, and are the masses of the two bodies/objects attracting each other via gravitational force. In our case, one is the mass of the Earth =

and the other one,the mass of the Moon =

and lastly, "d" is the distance between to two objects. In our case:

d =

Since all these quantities are given in SI units, when we use them in the formula, our answer will result in the SI units of force "N" (Newtons):

which can be rounded to: F =

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).
