Based on the sped of the waves and the tension as well as the needed wave speed, the required tension is 13.5 N.
<h3>What is the required tension?</h3>
Given the initial tension and speed, the tension that is required can be found by the formula:
= Initial tension x (Required speed / Initial speed)²
Solving gives:
= 6 x (30 / 20)²
= 6 x 9/4
= 13.5 N
In conclusion, the tension required is 13.5N.

Answer:
Speed at the bottom of the roller coaster = 49.79 m/s
Explanation:
A new ride being built at an amusement park includes a vertical drop of 126.5 meters. Starting from rest, the ride vertically drops that distance before the track curves forward.
We have to find the speed at the bottom.
Here the gravitational energy fully converts to kinetic energy, so we equate it.
Gravitational energy = 
Kinetic energy = 
=
= 2479.4
Velocity, v = 49.79 m/s
Answer:
Class 1 Levers: Moving the fulcrum closer to the load will increase the mechanical advantage. Moving the effort farther from the fulcrum will increase the mechanical advantage.
Explanation:

The answer is probably going the be C. Friction
It is like tranferring energy to another object
