Is the Radius of Curvature of a Concave Mirror Always Positive?

AI Thread Summary
The discussion centers on the radius of curvature of a concave mirror and whether it is always positive. A participant mentions an attachment containing their question and solution, which is in a zipped format. Another user suggests that using simpler formats like Paint or a text editor would be more accessible than a zipped Excel file. The conversation highlights the importance of clarity and ease of sharing information in technical discussions. Overall, the topic emphasizes the need for straightforward communication in physics-related inquiries.

The object distance of a real object from a lens is always positive.

By the way, is not it easier for you to draw in Paint, for example, and write in a text editor? this zipped xls file is a bit strange.

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...
