All of the following involve waves of electromagnetic energy except the rumble of thunder during a storm.

Electromagnetic waves are used to transmit long/short/FM wavelength radio waves, and TV/telephone/wireless signals or energies. They are also responsible for transmiting energy in the form of microwaves, infrared radiation (IR), visible light (VIS), ultraviolet light (UV), X-rays, and gamma rays.

The correct answer between all the choices given is the second choice or letter B. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

Answer:

B. The rumble of thunder during a storm

Explanation:

A. Sunlight shining on a plant leaf

All visible light coming from different sources is a part of electromagnetic waves.

C. Radios receiving signals through air

Radio waves are part of electromagnetic waves which is of least energy and largest wavelength

D. Watching videos on a computer screen

While watching videos we are receiving the light waves from the television and other ultraviolet waves coming from the source. These both are part of electromagnetic waves

So correct answer will be

B. The rumble of thunder during a storm

because it is a part of sound waves which travel through air

FrozenT [24]

Answer:

No, you can't keep on dividing the charge forever.

Explanation:

No, you can't keep on dividing the charge in that manner forever because the total charge of the stick is an integer multiples of individual units known as an elementary charge, which is the electron (e) charge (e = 1.602x10⁻¹⁹C).

Therefore the limit of the division of the original charge will be the electron charge since it is the smallest charge that can exist freely.

I hope it helps you!

A bell is ringing inside of a sealed glass jar that is connected to a vacuum pump. Initially, the jar is filled with air. What d

Mila [183]

Answer:

See Explanation

Explanation:

Sound is a mechanical wave. A mechanical wave requires a material medium for propagation. This means that sound waves must be carried in air. If there are no air molecules, sound waves can not travel.

When air is gradually removed from the jar by the pump, the sound intensity from the bell gradually decreases owing to the fact that air which is the medium through which sound waves are propagated is gradually being removed from the jar.
