In a cd player, where is the potential energy stored?
Where does does it change form?
Where is the kinetic energy released?
What happens to the mass in the leaves of a tree when the tree burns??
PLEASE ANSWER ALL OF THE QUESTIONS!!
A CD player, when playing, gets the energy required to turn the disc, operate a disc-reading laser, and emit an electrical sound signal to speakers, from an electrical source. That electrical energy could come either from a wall outlet or batteries.
When trees burn, the mass of the leaves and other parts is converted to CO2 and water vapor (H2O). Some ash will remain.
