Answer the following physics questions. Just the answer is fine no need to show your work.

An air column is open at both ends. The air in the column is caused to resonate by a tuning fork with a frequency of 256 Hz. The air column is 1.33 m in length. Which of the following diagrams best represents the resonating air column? i) 49A ii) 9*. iii Two flutes are being played at the same time. One of them is playing a note with a frequency of 560 Hz. The other is out of tune and a beat frequency of 6.0 Hz is heard. To adjust the out of tune flute the player incorrectly slightly lengthens his flute. This increases the beat frequency to 8.0 Hz. Remember that flutes act like air columns open at both ends. The original frequency (before it was lengthened) of the out of tune flute must have been Q 566 Hz Q 568 Hz Q 554 Hz Q 552 Hz A variable length air column is open at both ends. |t resonates when a 440 Hz tuning fork vibrates near one end. The length of the air column is slowly increased until the next resonance is heard. By what length, in centimetres, has the column's length been increased? A Spherical wave source is producing sound waves with an intensity 0.0250 W/m2 at a distance of 1.10 m from the source. How long will it take the source to produce 10.50 Joules of sound energy? Give your answer in seconds to 2 decimal places. Do NOT include units in your answer. Your Answer: l: Your
