Yes, you would need an electric lamp to read the music when it's dark.
fan converts electric energy into magnetic and further mechanical energy
Several ways. Mechanical Energy to Electrical Energy: Generators and Alternators Chemical Energy to Electrical Energy: Batteries Fuel Cells Thermal Energy to Electrical Energy: Thermocouples
chemical energy
the MRT trains make use of electrical energy to change into mechanical energy
Based on the conservation of energy principle, the other form of energy produced by the light bulb would likely be heat energy. Since not all electrical energy is converted into radiant energy, the leftover energy would typically be dissipated as heat.
Kinetic energy to electrical energy
It uses electrical energy to make thermal energy.
Electrical energy
A turbine.
The energy that is used to make a machine run is electrical energy.
The verb in the sentence is "needs to be tuned." To make it present tense, you would say "The piano needs to be tuned."
