What is the average density of a neutron star that has the same mass as the sun but a radius of only 20.0 km?

Explanation:

Density is a characteristic property bodies and materials, and is defined as the relationship between the mass and the volume , as shown below:

 (1)

In the case of the neutron star, we know it has the same mass as the Sun:

And its radius is

On the other hand, if we assume this neutron star has a spherical shape, its volume  can be calculated by the following formula:

  (2)

  (3)

  (4)

Substituting (4) in (1):

 (5)

Finally:

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

the answer is a 3.8cm
