Homework Statement



Asking me for total resistance



The Attempt at a Solution



I added the one in parallel first which is (1/5 + 1/5)=2.5ohm

Then added 9ohm + 2ohm + 2.5ohm = 13.5ohm( which i think it is the total resistance)
but the right answer should be 3ohm.

teehee

its 1/9 + 1/4.5 = 4.5/40.5 + 9/40.5 = 13.5/40.5

Therefore 40.5/13.5 = 3ohm
 

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 '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...
