Total Force on 8.00m Wide Aquarium Wall Increase

AI Thread Summary
The discussion focuses on calculating the increase in total force on an 8.00m wide aquarium wall when the water depth rises from 2.00m to 4.00m. Participants emphasize the need to establish an equation for pressure versus depth to solve the problem. The pressure at a given depth is crucial for determining the force exerted on the wall. A referenced homework page contains the answer but lacks clear explanations for the calculations. Understanding the relationship between pressure and depth is essential for solving this physics problem.

A large aquarium of height 5.00m is filled with fresh water to a depth of 2.00m. One wall of the aquarium consists of thick plastic of 8.00m wide. By how much does the total force on that wall increase if the aquarium is next filled to a depth of 4.00m.

The problem probably wants you to start by writing an equation for the pressure vs depth. Can you do that...?

Btw, we have a homework section...
 
Thanks for being completely unhelpful.

the answer is on that page although it's stupid since they haven't explained what they did and why.

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...
