    Convert Wavelength
AI Thread Summary
To calculate the frequency of sound emitted by bats with a wavelength of 3.5mm, it is necessary to convert the wavelength to meters, resulting in 0.0035m. The speed of sound in air at 30 degrees Celsius is calculated as 349.4 m/s. Using the formula V = wavelength * frequency, the frequency is determined to be approximately 99829.6 Hz. Converting the wavelength is essential for accurate calculations. The discussion confirms that conversion to meters is required for proper frequency determination.

Homework Statement



The sound emitted by bats has a wavelength of 3.5mm. What is the sound's frequency in air? Assume that the bat is flying through air with a temperature of 30 degrees C.

Homework Equations



V=331.4 + 0.6*Temp.C
V=wavelength*frequency

The Attempt at a Solution



V= 331.4 + 0.6(30)
V=349.4m/s

V=wavelength*frequency

349.7m/s=0.0035*f
f=99829.6hz

The only thing I'm not sure about is did I need to change the 3.5mm to .0035m?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
