Astronomers believe there are something like 100 million neutron stars in the Galaxy, yet we have only found about 2000 pulsars in the Milky Way. Give several reasons these numbers are so different. Explain each reason.

Explanation:

There are only few supernovae that can be observed in our system. Class II supernovae formed due to explosion of large stars, that are found in most remote areas of the galaxy, may occur on a Milky way disk and are obscured by dust and gas.Now to see a pulsar, it is important to point to the radiation beam provided by the pulsar in our vision. So we will not be able to sense the pulsar, even though it occurs.

One other explanation is that the radiation strength from the pulsar decreases considerably with time (the magnetic field necessary for the development of radiation appears to decay rapidly). The pulsar eventually loses its brightness becomes more like a neutron star.

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

thermal energy is the answer
