What are the different forms of energy that are transferred enabling us to hear the radio?
There is a transfer from Radio waves (electrical energy) to Mechanical energy (sound). When you listen to a radio, the electromagnetic energy of the broadcast is converted to electrical current, also electromagnetic energy, which is converted to mechanical energy by the speaker. The vibration of the speaker (mechanical energy) is converted to sound energy (pressure waves) which travel through the air to your ear and is converted first to mechanical energy in your middle ear and then to pressure in a fluid in your inner ear. That fluid pressure wave is converted to mechanical energy as it stimulates the hair cells in your inner ear and they release a nerve signal. The nerve signal is electrical energy which it converted to chemical energy between each nerve sell and then back to electrical energy to flow through the nerve cell - so the nerve signal is electro-chemical energy. And that is processed by your brain to let you hear the sound of your radio.
Is energy generated or destroyed?
Energy exists, it is not "generated" or destroyed, as stated in the First Law of Thermodynamics . In electric power plants, energy is converted from chemical energy to mechanical energy to electrical energy.
Which energy transfer takes place when a mobile phone rings?
It's a combination of electrical energy that defines the ringing sound, mechanical energy as the speaker or transducer vibrates to cause air movement, and acoustical energy represented by the pressure waves in the air that bring those annoying ringtones to our ears. ;-)
Why is chemical energy the energy that is converted to thermal energy?
Various kinds of energy may be converted into thermal energy.In a fire it is chemical energy that is converted to thermal energy.However:In a nuclear reactor, nuclear energy is first converted to thermal energy, and eventually to electrical energy.In a fire chemical energy is also converted to light energy.In a battery chemical energy is converted to electrical energy.In braking systems kinetic energy is converted to thermal energy.
Example of mechanical energy into electrical energy?
Electric generator, dynamo are examples where mechanical energy is changed into electric energy. This is also known as Alternator. This was first designed by Nicholas.
When you turn on a fan electrical energy changes into?
The electrical energy is converted to kinetic energy and heat. The kinetic energy is first seen in the blades of the fan as they rotate. This kinetic energy is converted to air movement, another form of kinetic energy. The electrical energy isn't fully converted to kinetic energy but turns into heat. This is generated by the magnetic fields of the motor and friction. Both of these are considered to be losses of energy but in fact they are simply a conversion to a form of energy that is not of use.
When you turn on a electric fan electrical energy changes into which kind of energy?
First changes into magnetic energy that leads to mechanical energy along with some heat energy
What does a microphone convert electrical energy into?
First forget the energyy. Our ears and the microphone diaphragms are sensors which are moved by the sound pressure (not by energy). The acoustical sound waves are converted to electrical voltage waves.
What are the energy transformations in a toaster?
First, a toaster uses electrical energy. Then, it uses this electrical energy and the mechanical energy of you pushing on the lever to produce thermal energy, or heat, and sound as the object in the toaster pops up.
What is the advantage of using wing to create energy?
First of all, energy cannot ever be created. It cannot be destroyed either. What you CAN do with energy is change it from one type to another. For instance, when you switch on your electric stove, it starts converting electrical energy to heat energy. The energy in wind is called kinetic energy. Kinetic means 'Moving'. Windmills convert this kinetic energy to mechanical kinetic energy, which is converted to electrical energy. There is no advantage of using wind to make electrical energy. It could well change the weather or climate by extracting energy from the air. There is no advantage in terms of price, either.
Energy transfers in a washing machine?
Washing machine converts electrical energy into kinetic energy. It helps in washing the clothes.
How did Thomas Newcomen's invention affect us today?
Newcomen invented the first workable steam powered pump. The power of steam can be harnessed to converted heat energy into mechanical energy.
