What kind of energy is created when an energy conversion is happening?
Energy conversion takes place when one form of energy is converted to another form. An example would a turbine, which converts heat energy to mechanical energy, or a generator which converts mechanical energy to electrical energy, or an electric motor which converts electrical energy to mechanical energy. In all conversion processes energy is lost (i.e. it is converted to heat at a low temperature). The useful power output of a machine is always less than the power input, by a ratio called the efficiency, usually expressed as a percentage. Typical efficiency for an electric motor is 95%, for a car engine 25%.
When is mechanical advantage less than 1?
When the output is less than the input. Mechanical advantage is expressed as the ratio of the output to the input.
What kind of energy does a fluorescent light produce?
Main one is light energy. Also some heat is produced
How does the ideal compare with the actual mechanical advantage?
The actual mechanical advantage is usually less, due to losses.
Why does saving energy save money?
this is because u use less energy. LESS ENERGY = LESS TO PAY
Why does a motor produces less mechanical energy than the energy it uses?
It spends energy overcoming friction in the motor.
A motor produces less mechanical energy than the energy it uses because the motor what?
Yes this is what we call efficiency of the motor. We give 100 but the motor in turn gives 40, so its efficiency is 40%
A kitchen blender transforms electrical energy into mechanical energy Why is the amount of mechanical energy produced less than the amount of electrical energy used?
Losses are due to inefficencies of the motor, and friction on moving parts.
What would most likely happen if green plants were exposed to longer days in sunlight?

What is true about any mechanical system?
The useful energy output is always less than the energy input.
Quantum-mechanical model for the hydrogen atom which of the following transitions would produce light with the longer wavelength 3p2s or 4p3p?
A transition from 4p to 3p will produce light with a longer wavelength. This is because this transition is a smaller energy exchange than that of 3p to 2s (longer wavelength = less energy.)
A bicycle dynamo is attached to the rear wheel the generated electricity is send to the D C motor which in turn increases the speed of the front wheel by its rotation is it possible?
Not really. Apart from there being a bicycle in the middle you are basically hooking a motor directly to a generator, and physics won't allow you to get away with that. There are always losses due to friction and whatnot that turns into heat instead of useable power. The electrical energy delivered by the generator is always less than the mechanical energy fed into by the generator, and the mechanical energy delivered by the motor is always less than the electrical energy fed into it. What you could do is use regenerative braking, where every time you brake you collect that energy, store it in a battery, and then use that energy to help you get the bike back to speed.
What less energy a wave has the smaller its?
If it is a mechanical wave, then the lower amplitude waves would have less energy. If you are talking about electromagnetic waves, then higher frequency waves (shorter wavelength) have more energy, and lower frequency waves have less energy.
What are problems with alternitive energies?
Alternative sources are less efficient. They produce less amount of energy.
What if you have no backpressure on a motor?
the motor will run with full efficiency as designed. No resistance means less energy expenditure. motor doesn't have to compensate for in line obstruction.
What cars produce less Co2?
Hybrid cars produce less carbon dioxide because they run partially on an electric motor and partially on a gasoline engine. Therefore a hybrid will produce less CO2 than a car that relies solely on a gasoline powered engine.
