Answer:
i hope this helps some
Explanation:
The time-averaged power of a sinusoidal wave is proportional to the square of the amplitude of the wave and the square of the angular frequency of the wave. This is true for most mechanical waves. If either the angular frequency or the amplitude of the wave were doubled, the power would increase by a factor of four.
The speed of a wave is dependant on four factors: wavelength, frequency, medium, and temperature. Wave speed is calculated by multiplying the wavelength times the frequency (speed = l * f).
Answer:
is destroy.
Explanation:
Because it is one of the demerit of a machine
Answer:
Explanation:
Heat required to raise the temperature
= mass x specific heat x rise in temperature
= .34 x 4200 x ( 95 - 23 )
= 102816 J .
1 kWh = 1000 x 60 x 60 J
= 3600000 J
102816 J = 102816 / 3600000
= .02856 kWh .
