If a star’s radiation peaks in the ultraviolet region of the spectrum, what could you conclude?
it will not be able to be seen
it is a black hole
it is a very intense star
it is not a very intense star

It is a very intense star

Explanation:

As we know by Electromagnetic radiations the energy of spectrum in decreasing order is given as

1) Gamma Rays

2) X rays

3) Ultraviolet Rays

4) Visible Light

5) Infrared waves

6) Microwaves

7) Radio waves

So here we can say that ultraviolet rays are at peak intensity for the spectrum in the radiation which means major proportion of the spectrum is consisting this part of the electromagnetic waves

So here the star would be very intense due to large number of this spectrum.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
