The total energy equation would be Kinetic energy+Potential energy
Good morning!
Wind energy is closer to the energy provided by the Tides as both are governed by forces of nature. In addition, the two are considered renewable energy sources and generate kinetic energy. These kind of energy are often used in Brazil.

Answer:
245.25 Newtons
Explanation:
the gravitational force of the earth is 9.81 N/Kg
And so to work this out you would multiply 25 by 9.81 to give you 245.25
Explanation:
Since, it is given that one hand completes 3.19 vibrations in 8.46 sec. Therefore, in one second the number of vibrations will be as follows.
= 0.377 vibrations
Hence, frequency (f) = 0.38 Hz
Now, formula to calculate the speed is as follows.
v =
or,
=
= 1.57 cm
Thus, we can conclude that the wavelength is 1.57 cm.
