What is mechanical advantage?</h3>
Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system.
Mechanical advantage is also defined as the ratio of output force to input force in a system.
Mechanical Advantage = Output force / input force
12.5 = output force / 15.7
output force = 15.7 x 12.5
output force = 196.25 m
Thus, the height through which the water is lifted is 196.25 m.

Since angular speed is persistent, v/r is constant.
Where:
v is tangential speed;
and
r is distance from
axis.
Then equate v/r in both cases to get v in the second case.
Hence, speed = 2.2 x 2.1 / 1.4 meters
= 3.3 meters / seconds
Alternative solution would be:
w = 2.2 / 1.4 = 1.57
v = rw = 2.1 x 1.57 = 3.3 meters / seconds
Answer:
D) Synthesizers have always had a well-established presence in standard ensembles
Explanation:
As synthesizers are electronic music instruments that can create the sounds of many different musical instruments, they have been seen as a threat to many musicians since their invention.
