Can you give the answer choices.??
Answer:
the state of giving off light or glow.
Answer:
192.6 Hz
Explanation:
v = Velocity of sound in air = 335 m/s
Actual frequency = 200 Hz = f
Observed frequency = 208 Hz =
Speed of train =
Doppler effect when the source is moving towards observer
Doppler effect when the source is moving away from observer
∴ Frequency he observes as the train moves away is 192.6 Hz
Here we know that
now from kinematics we have
now from above all values we have
so final angular speed is -12.6 rad/s
