Rank these stars in terms of temperature from coolest to hottest star a emits mostly ultraviolet light along with visible and infrared light star b emits mostly visible light, along with some infrared light and a tiny bit of ultraviolet light star c emits mostly infrared light with some red light
The list of stars from coolest to hottest is:Star CStar BStar A
The temperature of light depends on the wavelength. Longer wavelengths are associated with cooler temperatures and shorter wavelengths with hotter temperatures. Infrared light is emitted in a wavelength longer than that of red visible light, while ultraviolet light has a shorter wavelength than the blue light at the other end of the visible spectrum.
This means that the emission spectrum of Star A is the most energetic (and therefore hottest) as it's light is mostly of a shorter wavelength.
star h is the most luminous
star a is the hottest
The hottest star is A.
The most luminous is H.
The speed is 0.956 m / s.
The kinetic energy is equal to the product of half of an object's mass, and the square of the velocity.
K.E = 1/2 m
where K.E represents the kinetic energy,
m represents the mass,
v represents the velocity.
K.E = 1/2 m
1.10 10^42 = 1/2 3.26 10^31
= (1.10 10^42 2) / (3.26 10^31)
v = 0.956 m / s.
