Understanding Amplitude and Waveforms

AI Thread Summary
The discussion centers on understanding amplitude and waveforms in a conceptual context rather than through equations. One participant suggests that the longest waveform (option D) should have the highest amplitude. However, another points out that length does not guarantee amplitude, as a longer rod may be more massive and thus exhibit lower amplitude for the same energy. The conversation emphasizes the importance of considering resonance and coupling in determining amplitude. Ultimately, the relationship between length, mass, and amplitude is complex and requires careful analysis.

Homework Equations


This is a conceptual conception so no equations[/B]

The Attempt at a Solution



I believe answer is D since it is the longest and thus can have the highest amplitude.
Is it correct?[/B]

Being able to have the highest amplitude is no guarantee that it does have the highest amplitude.
For instance, the longest rod is also the most massive (all other things being equal) so it would have the lowest amplitude for the same energy.

This is a coupling/resonance question.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

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

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 hanging mass'

Thread 'A cylinder connected to a hanging 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...
