Ear defenders do not transfer the sound waves, instead they absorb them, so as little sound as possible is transferred to the ears

How do ear defenders work using the big idea of energy transfer?
It absorbs sound waves by increasing air resistance reducing the loudness of the waves. The energy is transferred into heat and the person wearing them can hear sounds at a quieter amplitude than the actual sound.
How does energy transfer by waves differ from energy transfer by a moving object?
In energy Transfer by waves, the energy moves through the the medium, for example the water, but isn't carrying the water with it. In energy transfer by a moving object the energy is traveling by means of an object. So, energy transfer by waves can be pictured as a person (the energy) swimming through water (the medium) and energy transfer through an object can be pictured as a person (the energy) riding a bicycle (the object) In the first case the energy itself is moving through a medium, where in the second case the energy is using its power to move by use of an object. Hope this helps you understand!
How can you maximise the rate of energy transfer to keep things cool?
you can maximise the rate of energy transfer by using materials that; -are good conductors -are painted Matt black -have the air flow around them maximised
Can you give an example of a sentence using the word radiation?
Radiation is energy transfer by electromagnetic waves.
What is the transfer of energy to an object using a force that causes the object to move in the other direction of the force?
Inertia.
How do you transfer heat energy by curtain?

What type of energy transfer is using a pot holder to lift a pot?
isnot energy type
Why em waves are used to transfer energy using antenna?
hi
Why can work be thought of a transfer of energy?
Because you are using force in a direction.

What is any living thing that makes food using the energy from the sun?
How do you transfer wind energy to electrical energy by using generator?
Wind turns the windmill which is attached to a generator. The more it turns, the more energy it produces.

What work is done without using energy?
If you mean "work" and "energy" in the physical sense, that isn't possible. "Doing work" can be understood as a transfer of energy; doing work requires energy.
What is the transfer of energy to an object using a force that causes the object to move in the other direction of the force?
Inertia.
