AI Thread Summary
To calculate the force exerted by water in a tank, the relevant equations include F = pA and Ph = ρgh, where p is pressure, A is area, ρ is fluid density, g is gravitational acceleration, and h is the height of the water. For the aquarium tank dimensions provided (100 cm long, 35 cm wide, and 40 cm deep), the force on the bottom can be calculated using the area and the pressure at the bottom. The force on the front window can be determined similarly, accounting for the height of the water. The density of water is essential for finding the mass and pressure, which are necessary to compute the forces accurately. Understanding these principles will help in solving the problem effectively.

Homework Statement



An aquarium tank is 100 cm long, 35 cm wide, and 40 cm deep. It is filled to the top.
What is the force of the water on the bottom (100cmX35cm) of the tank?
What is the force of the water on the front window (100x40) of the tank?

Homework Equations


this where i am unsure is it just f=mg? or F=pA. how do i get p?

The Attempt at a Solution


tried the equations above and got nowhere. also tried to solve using the density of water to find the mass but got nowhere so please advise thanks.

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 hanged 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...
