Answer: The star Alnilam is hotter
Explanation:
The question seems to be the continuation of another question, which is written below:
Use Wien's law to calculate the surface temperature of the star Alnilam in Kelvin. The peak wavelength 
of the star is 
So, by using <u>Wien's displacement law</u>, which relates the wavelength where the intensity of the radiation is maximum with the temperature 
of the black body, and expresed as:
(1)
Where:
is in Kelvin (K)
is the wavelength of the emission peak in meters (m).
is the Wien constant
We can find Alnilam's temperature and then compare it with the Sun's temperature (
):
(2)
(3)
(4)
As we can see 
, hence:
<h3>The star Alnilam is hotter</h3>
Yes. Velocity discribes both speed and direction of motion
