    Height Oil
AI Thread Summary
To calculate the height of oil in a U-tube, first convert the circular diameter of 5.60 mm into volume to determine how much height corresponds to 4.00 cm³ of oil. The oil level rises 6.8 mm above the water level on the opposite side, indicating a difference in height due to the added oil. A visual representation can help clarify the relationship between the oil height and the water level. Understanding the volume-to-height conversion is crucial for accurate calculations. The final height of the oil can be determined using these principles.

A U-tube of circular diameter 5.60 mm initally contain just water. If 4.00 milliliters(cm^3) of oil is added to the left hand side of the tube the level of the oil is 6.8 mm higher than the level of the water in the right hand side of the tube. Determine the height of the oil.

i'd give some help, but I'm actually clueless on how to start this.

First start by converting the diameter of the inner tubing (which they give) to milli-liters of volume which is how much oil they add. i.e how many mm of height is 1 milliliter of volume.

Then draw a picture showing the oil standing higher (and how much below that the oil/water interface is).
 
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 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...
