Explanation:
Initial speed of the incident water stream, u = 16 m/s
Final speed of the exiting water stream, v = -16 m/s
The mass of water per second that strikes the blade is 48.0 kg/s.
We need to find the magnitude of the average force exerted on the water by the blade. The force acting on an object is given by :

Here, 

So, the magnitude of the average force exerted on the water by the blade is 1536 N.

Answer:
The amount of work must be do to rotate the bar magnet is 151.2 J
Explanation:
Given:
Magnetic moment

Magnetic field
T
To find work do to rotate the bar magnet,
From the formula of work done in case of magnetic field,

Here
changes 0 to 180
But 


J
Therefore, the amount of work must be do to rotate the bar magnet is 151.2 J
