Question
Chapter 37, Problem 1Q
To determine
The relative temperatures of stars
Expert Solution & Answer
Answer to Problem 1Q
The reddish star is coolest, bluish star is hottest and whitish-yellow star temperature is greater than reddish star and lesser than bluish star.
Explanation of Solution
Color of the star determines its temperatures. Since, the temperature is related to the frequency of the emitted light, the light with greater frequency has greater temperature and the light with lesser frequency has lesser temperature.
Among red, whitish-yellow, and blue color, red color is at the lowest frequency, followed by a whitish-yellow. Blue color is at highest frequency. Therefore, the reddish star is coolest, bluish star is hottest and whitish-yellow star temperature is greater than reddish star and lesser than bluish star.
Conclusion:
Therefore, hottest star among the three is bluish star, the coolest is reddish star, and the whitish- yellow star is in between the bluish and reddish star.

- When current is flowing through the coil, the direction of the torque can be thought of in two ways. Either as the result of the forces on current carrying wires, or as a magnetic dipole moment trying to line up with an external field (e.g. like a compass). Note: the magnetic moment of a coil points in the direction of the coil's magnetic field at the center of the coil. d) Forces: We can consider the left-most piece of the loop (labeled ○) as a short segment of straight wire carrying current directly out of the page at us. Similarly, we can consider the right-most piece of the loop (labeled ) as a short segment straight wire carrying current directly into the page, away from us. Add to the picture below the two forces due to the external magnetic field acting on these two segments. Then describe how these two forces give a torque and determine if the torque acts to rotate the loop clockwise or counterclockwise according to this picture?
