The question here would be what is the volume of the room. The density of air that is given has no use. We simply multiply the dimensions given of the room to determine the volume.
<span>43.0m × 18.0m × 15.0m = 11610m^3 ( 3.28 ft / 1 m)^3 = 4.09 x 10^5 ft^3</span>
Answer:
Explanation:
given,
frequency of tuba.f = 64 Hz
Speed of train approaching, v = 8.50 m/s
beat frequency = ?
using Doppler's effect formula
v_s is the velocity of the source
v is the speed of sound, v = 340 m/s
now,
f' = 65.64 Hz
now, beat frequency is equal to
hence, beat frequency is equal to 1.64 Hz
