AI Thread Summary
The discussion revolves around applying Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL) to a circuit problem. The user inquires whether they can equate I1 to -I2, indicating a potential misunderstanding of current direction. Respondents confirm that this equation is valid under certain conditions and request the user to provide their equations for further analysis. The conversation emphasizes the importance of correctly applying KVL and KCL in circuit analysis. Overall, the thread highlights the need for clarity in understanding current relationships in electrical circuits.

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
