Air Temperature Affects 512HZ Tuning Fork Resonance

AI Thread Summary
The discussion revolves around determining the air temperature based on the resonance of a 512Hz tuning fork over a water-filled bottle. The first harmonic occurs when the water level is 17cm from the bottle opening, suggesting a relationship between the wavelength and the length of the air column. The fundamental frequency in a closed pipe has a wavelength that is four times the length of the pipe, which is relevant for calculating the speed of sound. Participants express uncertainty about the equations needed to connect wave speed, wavelength, and frequency. Understanding these relationships is crucial for solving the problem and finding the air temperature.

Homework Statement


a 512HZ tuning fork held over a bottle receives its 1st harmonic when the level of water is 17cm from the bottle opening. what is the temp of the air


Homework Equations


sound equation

Do you know an equation that relates the speed of a wave to the wavelength and frequency?
 
wavelength

is 17cm the wave length
 
What do you know about thewavelength of the fundamental frequency of a closed pipe?
 
not much all i know is that there's some kind of pattern
 
for a pipe closed at one end the fundamental frequency has a wavelength 4 times the pipe length.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
