Well when you hit the key, it triggers the hammer to hit the string , so that would be mechanical . Then , it hits the string that creates a vibrational wave , then , of course, it creates a sound wave . That's all I got .
An electric piano is but the classic piano is not powered at all except by the energy of the piano player as he/she hits the keys.
1. By the Piano. 2. Get the piano delivered and installed. 3. Bang on the Keys. If you actually want to play music on the piano it may take a lot longer.
5 but that's hard piano in easy piano you will only c 3
botty sweat
take the piano note down 3 half steps. example: a Bb on piano lowered 3 half steps would be a G
Power: electrical :finger:mechanical ( (kinetics)striker:sound.
The energy transformations that I would mention are as follows:Chemical Potential Energy --> Electrical Energy (In Battery)Electrical Energy --> Light Energy (In Bulb)Electrical Energy --> Heat Energy (In Bulb)Transformations 2 and 3 happen at the same time, because 3 is a side-effect of the intended transformation 2. I can't think of any other transformations, unless you wanted to consider the process of making the battery, or take the example of an unconventional flashlight.
chemical->heat
Yes. Chemical energy to mechanical and electrical energy and then mechanical energy to kinetic energy.
Yes. Chemical energy to mechanical and electrical energy and then mechanical energy to kinetic energy.
In most energy transformations, part of the energy is wasted. Much of the wasted energy is usually converted to heat.
yes because three times of energy transform
Electrical energy to kinetic energy
from electrical energy to mechanical energy
There are a few energy transformations when a gun is fired. Some of these include potential to kinetic energy, chemical to mechanical energy, and chemical to electromagnetic energy.
electrical energy to mechanical energy
=electric fan-electrical energy to mechanical energy!=
