It gets weaker, because that's a principle of electromagnets. The field force is directly proportional with tension.
Speed of wave = wavelength * frequency
Therefore, wavelength is 2.0 x 10^-8
Some of the techniques used by astronomers to determine the type of galaxy in which we live are:
- radio,
- optical,
- infrared
- x-ray astronomy
<h3>What is Astronomy?</h3>
This refers to the study of heavenly bodies and space and other things that space is made up of.
Hence, we can see that the reason why it is so difficult to determine the shape of our galaxy is that astronomers can only infer its presence from the motions of stars in the galaxy, and a precise shape is difficult to be determined.

The statement ‘A tertiary source is the most desirable source for a
researcher to use’ is false. It should be that your source is primary because
it is more reliable and is related to the research you have been working on.
