Precipitation is your answer. according to my science textbook, in a cold front, warm air and cold air interact and cause precipitation.
Answer:
Explanation:
1. They have different wavelengths - Because These radiations form a spectra that differs by the size of the wavelength.
2. They have different Frequencies (f) that is frequency = 1/ wavelength
(f = 1/wavelength)
3. They propagate at different speed though a non vacuum media (non vacuum media affect the speed based on the wavelength)
Answer:
An electromagnet is a magnet that uses electricity.
Explanation:

You just do the calculations.
