Physics

<h2>Answer:</h2>

The <u>interstellar medium</u> is the content of matter and energy that exists between stars within a galaxy.

In this sense, two components can be distinguished in the interstellar medium: dust particles and gas.

Dust represents 1% of the interstellar medium in mass, while the gas (consisting mainly of hydrogen and helium) represents 99% of the mass of the interstellar medium.

It should be noted that the interstellar matter is not uniformly distributed but is concentrated in molecular clouds.

enot [183]

Answer:

60°

Explanation:

Formula

360/n (if the number is an odd number) or

360/n-1 (if the number is even) (to arrive at an odd number)

SO. 5 is an odd number but not a multiple of 360, so we will use 6 an even number.

360/60-1

360/60=6 images

6-1 =5 images

Thus. the images formed will be 5.

If this standing wave is 48.8 meters long from end to end, what is the wavelength?
Mrrafil [7]

The wavelength of a standing wave is 8.13 m.

<h3>What is a wavelength?</h3>

The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.

The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.

The given data in the problem is;

String length(L)= 48.8 metere

Wavelength(λ)=?

The length of the wave having n nodes is found as;

L=nλ

Substitute the given value;

48.8 = 6λ

λ= 8.13 m

Hence, the wavelength of a standing wave is 8.13 m.
