**Answer:**

**Explanation:**

radius of earth = re

mass of the noon = m

mass of the earth = E

distance between earth and moon = r

acceleration of earth ae

force on earth = GMm / r²

acceleration of the earth

ae = force / mass

= GMm / (r² x M )

= Gm / r²

b ) The point on the earth nearest to moon will be at a distance of r - re

a_near = Gm / ( r - re)²

The point farthest on the earth to moon will be at a distance of r + re

a_ far = Gm / ( r + re )²

**Answer:**

magma forming above a subducting plate slowly rise into the overriding crust causing the formation of a volcano

<h3>Derivation of Conservation of Momentum</h3>

Applying Newton's third law, these two impulsive forces are equal and opposite i.e. If the time of contact is t, the impulse of the force F21 is equal to the change in momentum of the first object. The impulse of force F12 is equal to the change in momentum of the second object.

<h2>MARK ME BRAINLIST</h2>

Gravitational force is determined by **mass**

**Answer: Option B**

**<u>Explanation:</u>**

According to **Universal law of gravity**, the gravitational force is directly proportional to the product of the masses of the objects and inversely proportional to the square of the distance between the objects.

** **

Where,

G – gravitational constant =

= masses of two objects

r – distance between the objects

So, as per this law, **the gravitational force is found by mass.**

Yes it can.
