A galaxy 1.0 Billion parsecs away...
A galaxy 1.0 Billion parsecs away is expected to have a recessional velocity of a. 72 km/sec b. 720 km/sec c. 72,000 km/sec d. 720,000 km/sec e. 7.2 times 10^6 km/sec A 20-turn generator coil with area 0.016 m^2 rotates at 50 Hz in a 0.75-T magnetic field. Graph the induced emf as a function of time from t = 0 to t = 40 msec. Label the peak emf. A small light-bulb is fixed to a meter-stick's 0-cm mark, and at the 100 cm mark is a concave mirror with focal length 10 cm. At the 50-cm mark is a large convex lens with a focal length of 20 cm. Describe the final image formed by the mirror.
