Answer:
A) If you halve the wavelength, the electromagnetic radiation energy will double.
B) The energy of the electromagnetic radiation will halve if you halve the wavenumber.
C) When the frequency of the light is doubled, its energy will double.
Explanation:
The function for the light frequency is given as
The energy supplied to each electron is doubled by halving the wavelength, nearly doubling its kinetic energy by two after it is free from the metal. It is important to remember that for a given period of time, the number of electrons ejected will remain constant.

I believe this is a true or false question. The answer is true. The reason we have seasons is because of the earths tilt. So without it, we would simply have a constant weather pattern. That's why it can get so cold around the North Pole, the tilt is most drastic there. So the real answer is that it depends on where you live. If you're on the equator, then no, not having a tilt won't impact climate much, but the further you are from the equator, the more change there would be.
