Calculate the magnitude of the gravitational force exerted on a 4.20 kg baby by a 100 kg father 0.200 m away at birth (he is assisting, so he is close to the child). (b) calculate the magnitude of the force on the baby due to jupiter if it is at its closest distance to earth, some 6.29×1011 m.

(a). The magnitude of the gravitational force is

(b). The magnitude of the gravitational force is

Explanation:

Given that,

Mass of baby = 4.20 kg

Mass of father = 100 kg

Distance = 0.200 m

We need to calculate the gravitational force

Using gravitational formula

Put the value in to the formula

(b). We need to calculate the gravitational force

Using gravitational formula

Put the value in to the formula

Hence, (a). The magnitude of the gravitational force is

(b). The magnitude of the gravitational force is

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.
