An electromagnetic wave is produced by charged particles vibrating at a rate of 3.9 x 10^8 vibrations per second. the electromagnetic wave is classified as

The given electromagnetic wave is a radio wave.

Explanation:

Rate of vibration of the particle or frequency of the electromagnetic wave:

frequency = vibrations per second

Wave length of the electromagnetic wave will be given by:

The wavelength of of the electromagnetic wave is lying in the range of 1 mm to 100 km that is radio wave.

Hence ,the given electromagnetic wave is a radio wave.

write a paragraph or story to explain the transformation between potential and kinetic energy as shown in your picture or model.  

you should have at least 5 complete sentences with a main idea and supporting details.  

you must include the following words:  

potential energy

kinetic energy

mechanical energy

conservation of energy

dude, this is hard lol : ))

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
