What is a radio waves energy?
(The power of the radio transmitter) times (the length of time it continues to transmit)
Why do ac radios still have a soft hum after being turned off?
When you turn the radio off, you interrupt the AC supply from the wall outlet to the radio's power supply. If there's energy stored in the power supply components at the time, then the radio continues to operate on that energy. An AC power supply typically includes large-value electrolytic capacitors, which continue to power the radio for a short time until they're discharged.
A battery uses 810J of energy to run a portable radio for 30 minutes What is the power of the radio?
810 joules / 30 minutes = 810 joules / 1,800 seconds = 0.45 joule per second = 0.45 watt.By the way:-- The battery supplies the energy at the rate of 0.45 watt.-- The radio uses or consumes the energy at the rate of 0.45 watt.
When was Radio released?
Radio was released on 10/24/2003.
When radio is turned on electrical current flows through it what main type of energy is produced by the radio?
The electric power supplied to a radio is used to produce two types of energy: heat and sound. The sound is the useful part, and work is always continuing to find ways of producing less heat, because it only uses up electric power, and there are much better ways to keep our hands warm.
Heat energy released by an animal can power a radio.?
no
What type of energy is being released when a radio is playing?
its kinetic energy ;)
What type of energy is in a radio stereo?
well it is run on power so it is not energy
A radio is a design to turn sound energy into electrical energy what is another energy you released?
Heat
What is a radio waves energy?
(The power of the radio transmitter) times (the length of time it continues to transmit)
What is the difference between a radio waves power and its energy?
Power, in all situations is the rate of change of energy. If the power is constant, it can be found using the formula, "Power = Energy Used / Time taken". So, the power of a radio wave (in watts) is equal to the amount of energy it transmits (in joules) per second.In symbols:P = E/t
How do radio waves carry energy?
Radio waves are energy. Electromagnetic energy to be exact. The amount of energy a radio wave has will depend on the amount of power the transmitter has, the amount of amplification, the quality of the cable connecting it to the antenna and finally the antenna. The amount of energy is usually measured in watts.
What source of energy a radio uses?
Some radio sets run on batteries, others run using domestic power. They all run on electric power.

When you plug a radio into an outlet and turn it on you hear sound What type of energy transformation is taking place?
The main energy-changes are as follows: Chemical (in the battery) to electrical Electrical to sound
When was Animal Radio created?
Animal Radio was created in 2002.
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.
