Answer:
b) false
Explanation:
We know that rate of change of momentum is called force.
So
Force = rate of change of momentum
[tex]F=\dfrac{dP}{dt}[/tex]
We know that
P = m v
So
[tex]\dfrac{dP}{dt}=\dfrac{dm}{dt}V[/tex] (take velocity in constant and not changing with time)
[tex]F=\dfrac{dm}{dt}V[/tex]
So [tex]F=\dot{m}V[/tex]
So force exerted by jet depends on mass flow rate and velocity also.So our option b is right.
