Answer:
75000 Hz
Explanation:
f = V / λ (f= frequency, v=velocity of wave, lambda= wavelength)
alternatively, f = c / λ (f= frequency, c= speed of light- 3.00x10^8 m/s, lambda= wavelength)
f= [3.00x10^8 m/s]/[4000 m]
=75000 Hz
Answer:

Explanation:
Physics is that aspect of science that deals with nature and matter in relation to energy. Electricity is a source for energy
Explanation:
This is because gas particles are free to move as they are not held in place by strong molecular forces while particles in a solid are
