(a) Calculate the magnitude of the gravitational force exerted by the Moon on a 75 kg human standing on the surface of the Moon. (The mass of the Moon is 7.41022 kg and its radius is 1.7106 m.)

128 N

Explanation:

Using

F = Gm'm/r² Equation 1

Where F = Force, G = Universal constant, m = mass of the human, m' = mass of the moon, r = radius of the moon

Given: m = 75 kg, m' = 7.4×10²² kg, r = 1.7×10⁶ m

Constant: G = 6.67×10⁻¹¹ Nm²/kg²

Substitute into equation 1

F =  (6.67×10⁻¹¹ )(75)(7.4×10²²)/(1.7×10⁶)²

F = (3.7×10¹⁴)/(2.89×10¹²)

F = 1.28×10²

F = 128 N

Explanation:

Below is an attachment containing the solution.

jupiter

explanation:

it is so massive and has such a strong gravitational pull its likely prevented the formation of a planet between itself and mars in the asteroid belt

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
