AI Thread Summary

The discussion centers on the interpretation of a homework question regarding electrical circuits, specifically the implications of the phrase "without changing the circuit." Participants clarify that this phrase allows for the use of components already present in the circuit, such as a switch. The importance of understanding the effects of closing versus opening the switch is emphasized, particularly in relation to changing magnetic flux, which is crucial for the operation of dynamos and motors. The conversation highlights the need to analyze the circuit's behavior under different switch states. Understanding these principles is essential for solving the problem effectively.

The Attempt at a Solution

When it says, without changing the circuit, does it mean adding something else that is extra or does that mean i have to solve it without closing the switch?

Remember that what makes dynamos and motors work is changing flux not constant flux.

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 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:

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...
