AI Thread Summary
Ultrasound travels at a speed of 1500 m/s, and in 0.2 seconds, it covers a total distance of 300 meters. This distance accounts for the round trip of the ultrasound pulse, meaning it travels to the sea bed and back. To find the depth of the sea bed, one would divide the total distance by two, resulting in a depth of 150 meters. Participants are encouraged to show their work and use relevant equations to solve similar problems. Engaging with the homework section is advised for better guidance.

A submarine sends out a pulse of ultrasound to check how close it is to the sea bed. The reflected waves are detected 0.2 seconds later. Work out the total distance traveled by these detected waves. The speed of ultrasound is 1500m/s .

Welcome to the PF. :smile:

We can only help you if you show your best efforts to work on the solution. What are the Relevant Equations (involving speed, distance and time)? Can you show how to work with the Relevant Equations to start to figure out this problem?
 

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...
