AI Thread Summary
To calculate the maximum pressure exerted by a block of Niobium on one of its faces, the relevant equations involve determining the weight of the block and the area of the face in contact with the surface. The block's volume is found by multiplying its dimensions, and its weight is calculated using the density. The pressure is then derived by dividing the weight by the area of the face. The discussion highlights the importance of following forum guidelines and using the correct problem-solving template. The user acknowledges their oversight regarding the template and expresses that they have made progress in understanding the problem.

Ah it's cool, I think I figured it out, I just didn't think about one thing.
And I didn't realize about the template, I will ensure I follow it next time!
 
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...
