A circular coil of radius 0.120 m contains a single turn and is located in a constant magnetic field of magnitude 0.270 T. The magnetic field has the same direction as the normal to the plane of the coil. The radius increases to 0.320 m in a time of 0.0760 s. (a) Determine the magnitude of the emf induced in the coil. (b) The coil has a resistance of 0.670 Q. Find the magnitude of the induced current.

The difference in absolute magnitude between two objects at the same distance is related to their fluxes by the flux-magnitude relation. FA FB = 2.51(MB − MA) A distant galaxy contains a type I classical Cepheid whose period results in an absolute magnitude estimate of −6.3. If this star were placed next to our Sun (M = +4.8) and you observed them both from the same distance, how much more flux would the Cepheid emit than the Sun? FCepheid FSun = If a galaxy contains a supernova that at its brightest has an apparent magnitude of +11, how far away is the galaxy? Assume that the absolute magnitude of the supernova is −18. Hint: Use the magnitude-distance formula: d = 10(mV − MV + 5)/5 . The hydrogen Balmer line H? has a wavelength of 486.1 nm. It is shifted to 559.7 nm in a quasar's spectrum. What is the redshift of this quasar? (Hint: What is Δ??)
