Answer:
A
Explanation:
Work = F * d
Power = work/time or f *d / t
' A ' gives the highest amount of power
Answer:
b) √[(kx²/m) - 2gx]
Explanation:
The energy at the lowest point is equal to:
where:
Eelas = elastic energy [J]
k = spring constant [N/m]
x = extension of the spring [m]
We consider the lowest point, as the point where the potential energy is zero. At the moment when the person goes back through the point of the normal length of the elastic cord, it is this point that the person will have potential energy and kinetic energy.
Answer:
J.J. Thomson discovered <u><em>the electron</em></u> by experimenting with a Crookes, or cathode ray, tube. He demonstrated that cathode rays were negatively charged. In addition, he also studied positively charged particles in neon gas.

the answer is the underlined part of the answer section. I hoped this helped you a lot!! Study hard for whatever you are doing!!
The action that humans can take to reduce wave erosion is to build breakwaters in the ocean.
<h3>What is erosion?</h3>
The term erosion has to do with the washing away of top soil either by water or by wind. The control of erosion is a very important soil conservation effort.
Hence, the action that humans can take to reduce wave erosion is to build breakwaters in the ocean.
