What energy is wasted when blowing a whistle?
The energy wasted when blowing a whistle is converted to sound energy that is not useful for the intended purpose of the whistle, which is to produce a specific frequency of sound. Inefficient design or improper technique can also contribute to wasted energy.
What types of energy are used when blowing a whistle?
there is a little energy used, the point is you simply convert a wind energy into a sound energy. remember you cant create any kind of energy.
What is the energy that is not useful called?
The energy that is not useful is called waste energy. It is the energy that is not harnessed or converted into a form that can be utilized for work or other useful purposes.
What is the name of the amount of useful energy you get from a system?
That may refer to the system's efficiency (which is formally the amount of useful output power divided by the amount of input power).
How is energy efficiency determined?
Energy efficiency is typically determined by the ratio of useful energy output to total energy input in a system. It can be quantified by calculating the efficiency percentage, which is the amount of useful energy produced divided by the total energy input multiplied by 100. The higher the percentage, the more energy efficient a system is.

Useful and non-useful energy transfers for coal?

What is the energy transfer of a whistling kettle on a gas stove?
In a whistling kettle on a gas stove, energy transfer occurs primarily through thermal conduction and convection. The gas flame heats the kettle's bottom, transferring thermal energy to the water inside. As the water heats up and reaches its boiling point, it converts to steam, creating pressure that forces air through the whistle, producing sound energy in the form of a whistle. Thus, energy is transferred from chemical energy in the gas to thermal energy in the water and then to sound energy in the whistle.
A comparison of amount of energy before a conversion with the amount of useful energy after a conversion?
Usually, the amount of useful energy after a conversion will be less than the original energy. In no case can it be more.Usually, the amount of useful energy after a conversion will be less than the original energy.

What we energy that is not useful?
Waste energy
What are the social impacts of solar energy?
ask someone who cares bruv whistle that.
If electrical energy goes into a light bulb what useful energy comes out?
The useful energy that comes out of a light bulb is primarily in the form of light and heat. The electrical energy is converted into light energy that illuminates the surroundings and heat energy that warms up the light bulb and its surroundings.
Can energy be destroyed but not created?
Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.
If you have a device that has an energy efficiency of 0.7 and you put in 150 units of energy how many units of useful energy will you get out of it?
To calculate the useful energy output, multiply the input energy by the energy efficiency. In this case, with an energy efficiency of 0.7 and an input of 150 units, the useful energy output would be 0.7 × 150 = 105 units. Therefore, you would get 105 units of useful energy from the device.
Is gold useful in energy production?
Currently, gold is not useful in any form of energy production.
