What are the pulsar frequencies as seen from the spaceship

Reference no: EM13339323

Periodic signals from three pulsars reach the Earth. Signals from the first pulsar, denoted A, have a frequency of 400 Hz and come from a direction 10 degrees away from the direction of the galactic center. Signals from the second pulsar, denoted B, have a frequency of 900 Hz and come from a direction which is 30 degrees away from the galactic center. Signals from the third pulsar, denoted C, have a frequency of 1.1 kHz and come from a direction 120 away from the galactic center. A spaceship passes Earth, moving toward the galactic center at speed c=2, and observes the same pulsars.
