Answer:
A spinning turbine can generate electricity only in the form of an alternating current.
For fundamental frequency of a string to occur, the length of the string has to be half the wavelength. That is,
1/2y = L, where L = length of the string, y = wavelength.
Therefore,
y = 2L = 2*0.75 =1.5 m
Additionally,
y = v/f Where v = wave speed, and f = ferquncy
Then,
v = y*f = 1.5*220 = 330 m/s
There is no image!?...was there meant to be something attached?
Answer:
False
Explanation:
A wave is a disturbance that transfers energy from one place to another without transferring matter.
