AI Thread Summary
The discussion centers on determining linear density in Melde's Lab, which examines the relationship between frequency and tension in standing waves. Participants express confusion about how to experimentally determine linear density without having weighed or measured the string's length. It is clarified that weighing the string and measuring its length are necessary steps for this determination. The lack of these measurements leads to frustration, prompting one participant to consider addressing the issue with the teacher. Accurate experimental determination of linear density relies on these fundamental measurements.

This lab is basically the relationship between frequency and tension for a standing wave. One question I have though. In the lab I'm doing it states, "Calculate the linear density and determine it experimentally..." Calculating it is no problem, but how can I determine it experimentally? We never weighed or measured the total length of the string so I don't see how this can be done

You have to weigh the string and measure its length.

Thats what I thought and we never made those measurements. Time to yell at the teacher.
 

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 .
