Finding temperature using sound waves

AI Thread Summary
To find the temperature of a room using sound waves, the speed of sound in air can be calculated based on the time taken for echoes. In this scenario, two rocks are struck together 150 times over 92 seconds, with the rocks positioned 100 meters from a wall. The relevant equations involve the speed of sound, which is approximately 331.3 m/s at 0°C and increases by about 0.6 m/s for each degree Celsius rise in temperature. By determining the total distance traveled by the sound waves and the time taken, the temperature can be derived using the relationship between sound speed and temperature. Accurate resources for this information include physics textbooks or online databases that detail the speed of sound in relation to temperature.

hey
i need to know how to find the temperature of a room using the speed of the sound waves.
if two rocks are hit together and then each strike is in time with the echo (rocks are 100m away from wall), and the time to make 150 strikes is 92 seconds, what is the air temperature?
thanks

You are required to show your own work before we can offer tutorial help.

What are the relevant equations? What resource can you use to find what the propagation velocity of sound is versus temperature and density?
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
