Answer: The radio should be tuned to 100. 0 Mhz.
Explanation:
As radio waves are electromagnetic waves, like x-rays, UV rays, and all the wavelengths of visible light, they propagate in the free space at the speed of light: 3. 10⁸ m/s.
At any wave, there is a fixed relationship between the distance travelled by the wave along one cycle (which is called wavelength ) and the speed at which the wave oscillates (which is called the frequency of the wave), with the speed at which the wave propagates, as follows:
λ (wavelength) = v (speed) / f (frequency)
Replacing by the values, and solving for frequency, we have:
f = 3. 10⁸ m/seg / 3 m = 10⁸ 1/sec = 10⁸ Hz = 100. 0 Mhz
This is the radio channel to which must be tuned in order to listen the station with a wavelength of 3 m, in the FM band.

Answer:
Her computer is producing thermal energy, not heat.
Explanation:
Shelly informs her friend that she wants to repair her system because it has generated a lot of heat and therefore is smoking. Her device produces thermal energy but not heat because when she's working continuously and her system's CPU inside any blocked area at that time electricity pass through the CPU and blocked inside then it producing the thermal energy.
