The si unit of force is newton.
so, F is eqal to m*g
As stream discharge increases, only velocity increases.
<h3>What is discharge?</h3>
The discharge or volume flow rate is defined as the product of the velocity of the fluid and the area of cross- section of the pipe or tube.
Discharge Q = Area A x Velocity V
Q = AV
The discharge is directly proportional to the velocity of the fluid. When discharge increases, velocity is the only physical quantity that can be changed.
Thus, As stream discharge increases, only velocity increases.

The answer is 7 (its like the only question thats easy so far lol)
(D) The gravitational force between the astronaut and the asteroid.
Reason :
All the other forces given in the options, except (D), doesn't account for the motion of the astronaut. They are the forces that act between nucleons or atoms and neither of them accounts for an objects motion.
