The discussion revolves around confusion regarding the integration of dose rate in a homework problem. Participants express uncertainty about the "Q" in the problem, indicating that it is not clearly defined. The attached diagram is noted to lack specific questions, contributing to the confusion. There is a request for clarification on how to approach the problem effectively. Overall, the main issue is the lack of clarity surrounding the question and the integration process.

I don't understand to the Q but what i did is just integrating the dose rate , the Q is not clear to me can anyone help me

The "Q" is not clear to me either, possibly because I don't see an actual question anywhere. The attached diagram just seems to outline a general situation.
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 .
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...
