I am doing an experiment recording the speed of sound. I am using an open-ended cardboard tube that is 76.2cm (30") and the temperature in my room is 75 degrees or 23.89 celsius.

What is my speed of sound (using the speed of sound expression with explanation please)?

Given the length of my tube, what are my first five wavelengths that my tube should resonate (using the standing sound wave formula)?

What are my five wavenumbers (k) of the above (reciprocal).

What should my first five resonance frequencies (predicted) be? If i understand this correctly, I do this using the theoretical speed of sound calculated above together with the five resonance wavelengths also determined above.

Expert Solution

Expression for velocity of sound at a given temperature T Kelvin is

is the adiabatic constant R is the universal gas constant and M is the molecular mass of gas

Experiment is conducted at 23.89 C=(273+23.89) K=296.89 K

For air, adiabatic constant is 1.4 and molecular mass is about 0.02895 kg/mol

Putting the values,

For an open tube of length L, the resonance wavelengths are given by

n is an integer and n=1,2,3,4,....

Hence, the first five resonant wavelengths are given for n=1,2,3,4,5 viz-

The wave-numbers are just the reciprocals of above viz-

The first resonant frequency should be,

Hi, I am doing an experiment that is called NaBH4 reduction of acetophenone. I am having trouble understand the techinque/wording when using a sep funnel. These are some of the procedures below: 1. Pour the mixture into a separatory funnel and add 20 mL of ice water. Rinse the beaker with additional ice water (5 mL) and add the rinsing to the separatory funnel. Rinise the beaker with ether (2 X 15 mL), adding the ether to the separatory funnel....

I am doing a kids fishing game. right now I am doing it with 15 fish and number them 1-5. prize one the lowest value and prize 5 the highest value. What do I need to do for this? You can work with a partner or by yourself. I want you to invent a game with at least 12 different possible monetary outcomes. These outcomes need to include prizes other than money. You are going to charge people money (you...

I am doing this assignment using Kali Linux (COMPUTER SECURITY) I need to use crunch to generate all words which start with a lowercase letter, and then "YOURNAME(uppercase letter)", and then end with 2 digits. (e.g., "aIMAN23") I just need the screenshot of the crunch commands to follow. Using John the Ripper (In Kali Linux) I need the john command so I can use to Break test user's password: test:$6$fFEVS9TQoNU/aQsm$hxv5R1cSxwENUcdjxlI9WwbF8F3uruxAlDUf0vXaOAJRZnWhxr7zzLlFNJPGvc1pTdVV.lsuQkQh3mSjpy6SG/:18535:::::: I just need the screenshot to follow.

In this experiment, we have claimed to measure the speed of sound in air. To do this, we have used an audible frequency sweep. Why can we claim that the speed of sound will be the same over the bandwidth of the sweep? Is this assertion justified based on your results from experiment 2? Hint: Consider how sound (longitudinal pressure waves) propagate in a medium. (5 pts)
