Problem

A pulsar (rotating neutron star) emits radio pulses with period T0=1.00  sT_0 = 1.00\;\text{s} as measured in its rest frame. The pulsar moves directly away from Earth with velocity v=0.600cv = 0.600c. An astronomer on Earth receives these pulses and measures both their period and the total energy carried by each pulse. In the pulsar's rest frame, each pulse carries energy E0=1025  JE_0 = 10^{25}\;\text{J}. (a) What period TT does the astronomer measure between successive pulses? (b) What energy EE does the astronomer measure for each pulse?
