Same pressure points , 2 fluids u shaped tube

AI Thread Summary
The discussion centers on the pressure differences in a U-shaped tube containing two different fluids. It is established that the pressures at points C and D are equal, while the pressures at points A and B are not the same due to the presence of different fluids. The relationship between the pressures is explained using Pascal's principle, which states that pressure at a given depth is determined by the fluid density and height. The participants explore how the fluids can be in balance despite the unequal pressures at A and B. The conversation emphasizes the importance of fluid density in understanding pressure variations in the system.

Pressures at c and d are the same. Pressures at a and b are not the same. Do you know why?
 
Because of different fluids ?

And how the fluids are in balance if A and B pressures are not the same ?

yes
And how the fluids are in balance if A and B pressures are not the same ?
$$p_A+\rho_{left}g(x+h)=p_D$$
$$p_B+\rho_{right}g(x+h)=p_C$$

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...
