Answer:
F = 8552.7N
Explanation:
We need first our values, that are,

We start to calculate the relative velocity, that is,

With the relative velocity we can calculate the mass flow rate, given by,



We need to define the Force in the direction of the flow,




Answer:
I = 0.625 A
Explanation:
Given that,
Power of the light bulb, P = 75 W
Voltage of the circuit, V = 120 V
We need to find the current flowing through it. We know that, Power is given by :

I is the electric current

So, the current is 0.625 A.
