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
 = masses of two objects
r – distance between the objects
So, as per this law, the gravitational force is found by mass.

264Ns
Explanation:
Given parameters: 
Time of the push = 3s 
Force of push = 88N
Unknown: 
Impulse = ? 
Solution: 
Impulse is defined as the change in momentum of a body when force acts on it. 
   Impulse = Force x time
Inputting the parameters: 
     Impulse = 88 x 3 = 264Ns
