If you're using the machine to heat your workshop, it's 20% efficient.
If you're using it to do work, it's 80% efficient.
The definition of the period of a wave is the time that it takes for the wave to complete one cycle. As stated in the problem, the certain water wave completes one cycle in 2 seconds. From this information alone, we can conclude that the period of the wave is indeed, 2 seconds.

The tendency of a body to oppose any change in its state of rest is known as inertia of rest.
Example :
1 ) A person standing in a bus Falls backward when the bus suddenly starts moving forward.
Reason》When the bus Moves, the lower part of his party begins to move along with the bus by the upper part of his body continues to remain at rest due to inertia of rest.
That is why, a person Falls backward when the bus suddenly starts.

Answer:
Clyde will provide greater impulse
Explanation:
We have given that Al exerts a force of 200 N for 5 sec
We know that impulse is given by, impulse = force ×time = 200×5 =1000 N-s
Bill exerts a force of 500 N for 2 sec
So impulse = 500×2 = 1000 N-s
Now the force exerted by Clyde 300 N for 4 sec
So impulse = 300×4 = 1200 N-s
From above calculation we can see that Clyde provide greater impulse than any other
The formula for acceleration is the velocity times the inverse of time so it would be 21 times 1/13. So roughly 0.0769... is the acceleration(m/s^2).
