Musya8 [376]

Answer:

When observed from Earth, the wavelengths of light emitted by a star are shifted toward the red end of the electromagnetic spectrum because: the star is moving away from planet Earth.

A star is a giant astronomical or celestial object that contains a luminous sphere of plasma and bounded together by its own gravitational force.

A redshift can be defined as a displacement (shift) of the spectral lines of celestial or astronomical objects toward longer wavelengths (the red end of an electromagnetic spectrum), as a result of the Doppler effect.

Hence, a redshift is considered to be a subtle change in the color of visible electromagnetic radiation from stars (starlight), as observed from planet Earth.

In conclusion, a redshift occur when observing a star from planet Earth because the star is moving away from planet Earth.

Name two units for measuring the diameter of nucleus atom.

Evgesh-ka [11]

The two units for measuring the diameter of nucleus atom are femtometre and metre.

How do you measure the size of the nucleus ?

Nucleus size is expressed in fermi, often known as femtometers. between a lighter and a heavier nucleus. Despite its modest size, the nucleus contains the majority of an atom's mass. The weight or mass of the atom's nucleus and neutrons are determined by neutrons.

femtometre (fm), which equals $10^{-15}$ metre.

A nucleus' diameter largely depends as to how many particles it contains, from about 4 fm for a light nucleus like carbon to 15 fm for a heavy nucleus as lead.

Conductors and Insulators

grin007 [14]

Answer:

<h2>Conductors</h2>

The substances which allow an electric current to pass through it is called conductors.

Example: Metals like copper,iron ,graphite etc.

<h2>Insulators</h2>

The substances which do not allow the electric current to pass through is called Insulators.

Example: Glass, dry wood ,plastic etc.

Hope this helps...

Good luck on your assignment...
