What else can I help you with?
Is all the energy transferred during an energy change always useful?
No, not all energy transferred during an energy change is always useful. Some energy may be lost as heat or sound, decreasing the overall efficiency of the energy transformation. This is known as energy wastage, and it occurs in many natural and human-made processes.
What happens to the energy that is not usefully transferred by the solar cells?
The energy that is not usefully transferred by solar cells is typically dissipated as heat. This occurs when the energy is not converted into electrical energy due to inefficiencies in the solar cell's conversion process.
Is there a limit to how many times energy can be transferred?
In theory, energy can be transferred multiple times in various forms such as from one object to another or between different forms like potential and kinetic energy. However, with each transfer, some energy may be lost as heat due to inefficiencies in the system, so there is a practical limit to the number of times energy can be transferred before it becomes too low to be useful.
What useful energy transfers in a wind turbine and a generator?
Kinetic energy is transferred to electrical 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.
What is useful energy transfer when coal is burnt?
Chemical energy is transferred to electrical energy! :) :p

How can you calculate the efficiency of an appliance in terms of power?
vague question. Efficiency in terms of energy = useful energy/total energy x 100 vague question. Efficiency in terms of energy = useful energy/total energy x 100

An ecologist is studying how energy is transferred between organisms within an aquatic ecosystem Which model is most useful for the ecologists research?
the food chain
What is wasted energy lost as?
Wasted energy is often lost as heat. When energy is transferred or transformed, some of it becomes unusable or dissipated in the form of heat due to inefficiencies in the system. This lost energy cannot be harnessed to do useful work.
What is the efficiency equation for energy?
The efficiency at which energy is transferred from one trophic level to another is called ecological efficiency.it is estimated that only a 10 percent of available energy is transferred
What ue is the kind of energy you want to be transferred?
The type of energy you want to transfer is known as the input or source of energy, which is typically converted into a different form of energy for the desired purpose. For example, electrical energy may be input to a motor to produce mechanical energy.
What is the useful energy transfer in a wind turbine and generator?
The useful energy transfer in a wind turbine and generator is the conversion of kinetic energy from the wind into electrical energy. As the wind turns the blades of the turbine, the rotor shaft connected to the generator spins, producing electricity through electromagnetic induction. This electricity can then be used to power homes, businesses, or stored for later use.
