- Astrology: Why is carbon monoxide important for stars?5. A star whose temperature is 8000 K has a peak wavelength of 362.5 nm, according to Wien's Law. If the star is in the Andromeda Galaxy, which is moving towards us at about 402,000 km/hour, what would an observer on Earth see as the peak wavelength for this star (show your work, and use c = 300,000 km/s)?Pro expert hero Hand written solution is not allowed.

- A homogeneous pulley with two grooves consists of two wheels which turn together as one around the same axis. The moment of inertia of the two wheels together is ICM = 40 kg m2. The radii are: R1 = 1.2 m and R2 = 0.4 m. The masses that hang on both sides of the pulley are m1 = 36 kg and m2 = 12 kg. We will assume that the masses of the ropes are negligible. Determine the angular acceleration of the pulley, acceleration of the masses, and the tensions of the ropes.15 On a Hertzsprung-Russell diagram, where on the main sequence would we find stars that have the greatest mass?

They can be measure out to ~ 80 Million light years Once the period is measured, the luminosity is known Early 1900s astronomers used them to map out our galaxy more accurately. All of them have about the same luminosity; knowing their apparent magnitude allows us to calculate the distance.
