What is the energy equivalent in tons of coal for operating a radio for 4 years when a radio uses the energy equivalent of one twentieths of coal per year?

What is the energy equivalent in tons of coal for operating a radio for 4 years when a radio uses the energy equivalent of one twentieths of coal per year? First look at the 1/20 ton then invert the 1/4 to get 4/1 then multiply to get the answer of 1/5. 1/20 * 4/1=1/5

How is energy wasted by the radio?
A radio , when operating may give off a little' heat'. This is wasted energy. We don't want heat from a radio , we want 'sound'.
Is a radio a sound energy?
A radio produces sound, and therefore sound energy. The radio waves, however, are electromagnetic energy, not sound. The function of a radio is to convert that electromagnetic energy into sound energy.
What energy conversions occur in a radio?
In a radio you have the conversion of radio wave energy to sound wave energy.
What radio net do you have to be on when operating on the ramp?
Ramp Net
Does a radio use sound energy?
yes,because radio is an example of sound energy...
What is the transformation of energy of battery-operated radio?
what is the transformation of energy in battery-operated radio
What is the transformation energy of battery-operated radio?
what is the transformation of energy in battery-operated radio
Why was the radio named as such?
The "radio" is named as such to reflect the type of energy used to cause the radio instrument to operate. That being "Radiant Energy."
Is a radio and example of radiant energy?
Yes. Radios use radio waves which are radiant energy.
How energy is transformed in battery operated radio?
A radio receiver transforms electrical energy to acoustic energy
What type of energy transformation does a radio signal have?
The radio signal itself, of course, is not an energy transformation - energy transformation means that energy is changed from one type to another. There is an energy transformation when the radio signal is created, and another one when it is absorbed.
Does a radio converts from electrical energy to sound energy?
yes. because you have to plug in the radio which is electrical and then when you turn on the radio it produces sound. even if it's a battery powered radio, the battery stores energy in the form of chemical energy, but delivers it as electrical energy, so even in that radio, the radio is converting electrical energy to sound energy when you turn on the radio. What about an old-fashioned "crystal set" that has no battery and doesn't plug into the wall ? Even that one converts electrical energy into sound. The only electrical energy it ever gets is what it picks out of the air that got transmitted from the radio station. That's very very little energy, which is why the sound from a crystal set is always so weak.
