Answer:
0.906
Explanation:
Let g = 9.81 m/s2. We can calculate the rate of change in potential energy when m = 201kg of water is falling down a distance of h = 131m per second
So the efficiency of the water turbine is the ratio of output power over input power:

Hello! Here are your answers!
SCALAR: Scalar quantities have a size or magnitude only.
VECTOR: Vector quantities have both magnitudes and direction.
Explanation:
They are alike as they are both used to explain physical quantities and represent the magnitudes or sizes of the physical quantities...
They are different as VECTOR quantities describe an objects DIRECTION as well as magnitude whilst SCALAR doesn't
ie...<u>SCALAR:</u> MASS, TIME
<u>VECTOR:</u> VELOCITY, ACCELERATION...
I HOPE THIS HELPS!!
Sound waves are mechanical waves while electromagnetic waves are not. Thus, sound waves require a medium for propagation while electromagnetic waves do not. Sound waves are produced by mechanical vibrations and propagate through liquid, air and plasma as longitudinal waves. While electromagnetic waves are <span>produced by </span>accelerating or decelerating<span> charged particles. It also contain a</span> <span>magnetic field. Because they are not mechanical waves, it can propagate through a vacuum as well as air, liquid, and solid.</span>
