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 value is
Explanation:
Generally the moon's radial acceleration is mathematically represented as
Here is the angular velocity which is mathematically represented as
substituting for T(i.e the period of the moon ) we have
=>
From the question r(which is the radius of the orbit ) is evaluated as
substitute for R and H
=>
So
