What is the speed of sound in the metal?

AI Thread Summary
The discussion centers on a metal tube where a hammer strike produces two distinct sounds heard 2.5 seconds apart. This delay is attributed to one sound wave traveling through the metal and the other through the air inside the tube. The speed of sound in the metal can be calculated using the equation t = L/v, where L is the length of the tube and v represents the speed of sound in both mediums. The participants agree that the solution involves comparing the speeds of sound in air and metal to explain the time difference. Understanding these concepts is crucial for accurately determining the speed of sound in the metal.

Homework Statement


A metal tube with length 931m is hit with a hammer. On the other end two sounds with time delay of 2.5 seconds can be heard. What is the reason for this? What is the speed of sound in the metal?

Homework Equations


t=L/v


The Attempt at a Solution


I think the solution is quite simple, I'm just not sure if it is correct. The two sounds which can be heard are two waves - one which travels through the metal, the other through air inside. The speed of sound in the metal can be determined from this equation:
L/v1-L/v2=2,5s. (v1 is the speed in air, v2 in the metal)

I'd say you were correct.
 

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...
