Does an energy conversion makes the telephone a useful machine explain?
W-E-L-L, this question is on a directed reading 2 science thing homework. Make an educated guess.
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.

How a machine transforms energy into waste energy?
A machine transforms energy into waste energy through the process of converting the energy into different forms, such as heat, sound, or vibration, that are not useful for the machine's intended purpose. This waste energy is typically released into the environment as a byproduct of the machine's operation, leading to inefficiencies in the energy conversion process.
What is the amount of useful energy you get from an energy conversion called?
The amount of useful energy obtained from an energy conversion process is referred to as energy efficiency. It is calculated by dividing the useful output energy by the total input energy and expressing it as a percentage. Energy efficiency is an important factor in determining the overall effectiveness and sustainability of an energy conversion process.
What is a comparison of the amount of energy before conversion with the amount of useful energy after conversion?
The amount of energy before conversion is typically higher than the amount of useful energy after conversion due to energy losses during the conversion process. These losses can occur in various forms, such as heat, sound, or light, reducing the efficiency of the conversion process. It is essential to minimize these losses to optimize energy efficiency.
What percentage of energy is converted into useful energy?
It depends on the efficiency of the machine. No machine is perfect and there are always losses and waste. Usually the losses are a greater percentage than the useful energy.
Why is the amount of useful output energy always less than the input energy?
The reason the useful output energy is always less than the input energy is due to inefficiencies in the energy conversion process. Some energy is always lost as heat, sound, or other forms of energy during conversion, reducing the amount of energy available for useful work. This decrease in useful output energy is described by the concept of energy conservation and the second law of thermodynamics.
What is an efficiency ratio?
The efficiency ratio for a machine usually refers to the ratio of the useful energy available from a machine and the energy put into it.
What is a mechanical Effeciency?
Mechanical efficiency is a measure of how well a machine converts input energy into useful output energy. It is calculated by dividing the actual output power of the machine by the input power and multiplying by 100% to get a percentage. A higher mechanical efficiency indicates that less energy is lost in the conversion process.
What are the Useful types of output energy in a washing machine?
Useful types of output energy in a washing machine include mechanical energy for agitating and spinning the drum, thermal energy for heating water, and electrical energy for powering the control panel and motor.
What does energy efficiency?
Energy conversion efficiency is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The useful output may be electric power, mechanical work, or heat.
What Useful energy is in a washing machine?
Useful energy in a washing machine includes electrical energy to power the motor and controls, kinetic energy for agitating and spinning the drum, and thermal energy to heat water for washing. These forms of energy work together to clean clothes efficiently.
