AI Thread Summary
The discussion centers on the value of the constant k in the latent heat equation L = kIV∆T/∆M. The poster is uncertain whether k is 0.239 or 0.739 and seeks clarification on its correct value. They also request definitions for the variables I, V, and k, although they believe they understand their meanings. There is a suggestion that k may represent a constant related to power loss to the surroundings. Accurate information on these points would be beneficial for the poster's understanding.

I have a derived equation for latent heat, L = kIV∆T/∆M. I was just wondering what the value for k is. I have it written down in my notebook but i can't tell if i wrote a 2 or a 7, so it should be .239 or .739. If anyone knows it'd be appreciated, thanks.

It would be helpful if you could state the exact meaning of the variables, especially that of I, V and k, though I think I know what they mean...

I also have a feeling that k is a constant describing loss of power to the surroundings, but I can't be sure until you provide more info.

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...
