+Many of the stars in the sky are actually binary stars, in which two stars orbit about their common center of mass. If the orbital speeds of the stars are high enough, the motion of the stars can be detected by the Doppler shifts of the light they emit. Stars for which this is the case are called \emph{spectroscopic binary stars}. Figure shows the simplest case of a spectroscopic binary star: two identical stars orbiting their center of mass in a circle. The plane of the stars' orbits is edge-on to the line of sight of an observer on the earth. The light from each star in the binary system varies from its maximum frequency to its minimum frequency and back again in 11.0 days. Determine the orbital radius \( R \) and the mass \( m \) of each star. Give your answer for \( m \) in kilograms and as a multiple of the mass of the sun, \( 1.99 \times 10^{30} \) kg. Compare the value of \( R \) to the distance from the earth to the sun, \( 1.50 \times 10^{11} \) m.

+A coil with 4 turns, radius \( 0.800\ \text{cm} \), and resistance \( 0.250\ \Omega \) is placed between the poles of an electromagnet whose field increases from zero at \( t = 0 \); the current \( i \) induced in the coil as a function of time \( t \) is shown. Calculate the magnetic field at the location of the coil for \( t = 6.00\ \text{s} \).
