Cell phones contain rechargeable batteries that transform chemical energy into electrical energy. when using your cell phone, electrical energy is first transformed into that are transmitted through the air. a) sound waves. b) sound energy. c) mechanical energy. eliminate d) electromagnetic waves

the answer is d

Option (D) is the correct answer.

Explanation:

Electric field and magnetic field result in the formation of waves known as electromagnetic waves.

In cell phones, when chemical energy is converted into electrical energy then electrical energy first transforms into electromagnetic waves which travel through air.

After that this electromagnetic wave is transformed into sound energy due to which we are able to listen music, movies etc on our cell phones.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
