A survey that uses Type la supernovae as standard candles to measure the distances to galaxies, combined with spectroscopic analysis of those galaxies Select one: to obtain their redshifts and recession velocities, yields the data shown in the O a. The Universe is undergoing table. Use the data to sketch a diagram of velocity versus distance. Choose the accelerated expansion statement given below that can be O b. The Universe is contracting. inferred from the data. Velocities and distances to O c. The data does not provide sufficient galaxies information to determine the rate of Distance (Mpc) expansion of the Universe. Velocity (km/s) 10 730 O d. The expansion rate of the Universe is 250 16250 constant 500 30000 е. The expansion of the Universe is 800 40000 decelerating. 1000 45000
