Wavelengths of light are emitted when an electron is coming from an energized state back to its initial state. The energy that is omitted comes in the form of the wavelength. I'm not completely sure if this is totally the way to say it, but it is what I remember from chem last year.
A) the objects kinetic energy is transformed into mainly heat energy
That "heat energy" is called fricton
Answer:
The period of a pendulum does not depend on the mass of the ball, but only on the length of the string. Two pendula with different masses but the same length will have the same period. Two pendula with different lengths will different periods; the pendulum with the longer string will have the longer period.
Explanation:
gravity, fluid friction, and i think two more i just cant remember them
Answer:
Potential
Explanation:
This is because it has not yet fallen, and it has the potential to fall and turn into kinetic energy. When it starts falling, it will be kinetic.
