A pulsar is a stellar object that emits light in short bursts. Suppose a pulsar with a speed of 0.912c approaches Earth, and a rocket with a speed of 0.994c heads toward the pulsar. (Both speeds are measured in Earth's frame of reference.) If the pulsar emits 10.0 pulses per second in its own frame of reference, at what rate are the pulses emitted in the rocket's frame of reference?
