AI Thread Summary
To solve the fish distance problem, it's essential to recognize that the sound signal travels to the fish and back to the boat, meaning the total travel time of 0.483 seconds must be halved to find the one-way time. The speed of sound in water is approximately 1,484 meters per second. By calculating the distance using the formula distance = speed × time, the distance to the fish can be determined. Therefore, the fish are approximately 356.5 meters away from the boat. Understanding these principles is crucial for solving similar sonar-related problems.

I don't understand how I am suposse to solve this question using only 1 given
a) a deep sea fishing boat received an echo from a school of fish 0.483 s after transmission. How far away were the fish?
if anyone can help, it'll be appreciated

The sound (SONAR signal) must travel from boat to fish and back. How fast does sound travel in water?
 
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...
