Please answer part A

Three spaceships all broadcast a signal at the same frequency f0. Spaceship #1 is at rest, spaceship #2 is traveling away from #1 at a speed v, and spaceship #3 is traveling away from #1 in a direction opposite that of #2 and also at a speed v. Determine the following in terms of f0 when v = 0.40c.

(a) Frequency measured by #1 broadcast from #2

(b) Frequency measured by #1 broadcast from #3

(c) Frequency measured by #2 broadcast from #1

(d) Frequency measured by #2 broadcast from #3

(e) Frequency measured by #3 broadcast from #1

(f) Frequency measured by #3 broadcast from #2

An acoustic signal is composed of the first three harmonics of a wave of fundamental frequency 425 Hz. If these harmonics are described, in order, by cosine waves with amplitudes of 0.630, 0.900, and 0.650, what is the total amplitude of the signal at time 0.825 seconds? Assume the waves have phase angles θn = 0.
