Answer:
a)
b)
Explanation:
Given:
mass of the container,
displacement of the container,
Since the load is lifted using cable there will be weight acing downwards and the tension in the cable will act upward which will be equal in magnitude to the weight.
So,
(upwards)
Now the work done by the tension:
Now the work done by the gravity:
since displacement is in opposite direction to the gravity
Answer:
a.
Explanation:
Use accleration formula,
The initial velocity and final velocity is at zero. and t=10
So we got
so
a is the answer
I think it is the wave energy.
Wave energy also known as the ocean energy is the energy harnessed from the ocean or sea waves. It is a source of power that comes from the endless march of the waves as they roll into the shore then back out. Using wave energy is advantageous as they are environmental friendly as there are no harmful byproducts, and also the energy from waves can be taken directly into electricity-producing machinery and used to power generators.
The answer for this question is o power
