Weegy: If the frequencies of two component waves are 24 Hz and 20 Hz, they should produce 4 beats per second.
User: your boss asks you to adjust the temperature so that temperature so that a sound wave travels more quickly through the air. you increase the temperature from 30 c to 60 c. what's the velocity of the sound wave at this new temperature
Weegy: You adjust the temperature so that a sound wave travels more quickly through the air. You increase the increase the temperature from 30 C to 36 C. [ The velocity of the sound wave at this temperature is 352.6 Hz.
Solution:
velocity of sound in air = 331.5 m/s + 0.59 m/s* C times (the new temperature);
v = 331.5 + 0.59 * 36;
v= 352.6 Hz.

User: a surface receiving sound is moved from its original position to a position three times farther away from the source of the sound. the intensity of the received sound thus becomes
Weegy: A surface receiving sound is moved from its original position to a position three times farther away from the source of the sound. [ The intensity of the received sound thus becomes: Nine times as low.
