Circuit Current Field Induced Induced current Loop Magnetic Magnetic field

AI Thread Summary

The discussion revolves around understanding induced current in a loop circuit influenced by a magnetic field, specifically using Lenz's law. The participant has calculated the circuit's resistance as approximately 0.00427 ohms but is unsure how to proceed with the problem. Clarification on applying Lenz's law to determine the direction of induced current is sought. The participant expresses confusion and requests further assistance to advance their solution. Overall, the focus is on grasping the principles of electromagnetic induction in circuit analysis.

I know this is supposed to use Lenz's law, but I don't really understand it

V=IR

The Attempt at a Solution

I calculated the resistance of the circuit to be 6.4e-6 / .0015 = 0.00426666667, but that's as far as i know what to do

any help here? I'm really stumped on this one

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 .

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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...
