A headphone what useful energy does it have?
Sound energy.
A car that brakes suddenly comes to a screeching halt Is the sound energy produced in this conversion a useful form of energy?
because it have sound energy
What is the useful energy from an electric drill?
sound, also heat
Headphones useful and wasted energy?
usful energy will be that it make sound for the person to hear through it
What is the useful energy in a whistle?
acoustic energy, when you make sound it is audible because it is in sound waves that move through the atmosphere and into you ear to vibrate your eardrum
Useful and non-useful energy transfers for coal?
Useful: Energy Light Sound Non-Useful: Electricity C02

What is the useful energy from an electric drill?
sound, also heat
Headphones useful and wasted energy?
usful energy will be that it make sound for the person to hear through it
Is sound energy useful?
As long as it is not used manually in a destructive manner
Does an electric iron convert electric energy to heat and motion?
heat(useful energy) and sound(waste energy)
What is the useful energy in a whistle?
acoustic energy, when you make sound it is audible because it is in sound waves that move through the atmosphere and into you ear to vibrate your eardrum
What type of energy does a TV convert to?
Converts Electrical energy into the useful energy, light and sound. There will be some unwanted heat energy as well
Why does the amount of useful energy decrease when energy changes from one form to another?
Conversions of energy forms are lossy. For example, when mechanical energy is converted to electrical energy (such as happens in an electric generator), there is friction which leads to the escape of heat and sound energy. While the total amount of energy in all forms remains constant, the heat and sound energy are next to impossible to recapture, so this is considered a loss of useful energy.
Does an electric can opener convert electric energy sound energy?
Not likely - any machine wastes some energy; that would reduce the useful output energy.
What are useful and non-useful energy transfers for wind?
Example: TV. Electricity- Heat, light, sound. Useful energy transfers would be electricity- light, sound because that's what your TV actually needs, but electricity- heat would be wasted energy or a non-useful energy transfer because your TV does not need to produce heat, unless of course you can't afford central heating, but then isn't heating more important than a TV???? Summary: Useful energy transfer: The purpose of the object is fufilled by this transfer. Non-useful energy transfer: The purpose of the object is not fufilled by this transfer, and in effect, this transfer is a "side effect" of the useful energy transfer. These transfers waste energy.
