I have attached my work. I'm not asking for teh answeres as I've done them; but want to make sure I haven't made some silly mistake and have set things out rigth adn used the right triangles/formulae. Thank you very much in advance.

Ya !if no going wrong, for me, i also would use these formulae !:smile:
 
formulas are fine
hope you don't want us to check your calculations ...
 
Yes, I would appreciate it if you were to check out my calculations. What I was trying to iterate was that I'm not here to grab answeres without putting in the effort. I know sometimes I can make a silly mistake by missreading things or setting out incorrectly and .etc

I enjoy my physics and would like to know as much ap (as possible). Thank you very much for helping me and sorry for not making things clear.

P.S It would be nice if this forum accepted Word documents (.docx .doc).

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...
