Doppler Effect in Circular Motion

AI Thread Summary
The discussion focuses on calculating the highest and lowest frequencies heard by students from a 500 Hz sound generator being twirled in a circular motion at 100 rpm. Key considerations include determining the speed of the generator and the positions where it moves closest and farthest from the students. The Doppler effect equation is essential for finding the frequency shifts based on the generator's motion relative to the observers. The maximum frequency occurs when the generator is moving directly towards the students, while the minimum frequency is when it moves away. Understanding these principles allows for accurate frequency calculations in circular motion scenarios.

[SOLVED] Doppler Effect in Circular Motion

Homework Statement



A Physics professor annoys his students by tying a 500 Hz generator to a 60cm long string and whirling it around his head at 100 rpm. What are the highest and lowest frequencies heard by the students?

What is the equation for doppler effect?

What is the speed of the generator when the professor is twirling it? suppose the students are gathered at together right in front of the professor...

In the circular path of the generator when is the generator moving fastest towards the students... this gives the maximum frequency... when does it move fastest away from the students... this gives the minimum frequency.

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...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
