AI Thread Summary

To determine the force acting on a box sliding down a frictionless ramp inclined at 25 degrees, the weight of the box is given as 100N. The relevant equations involve calculating the component of gravitational force acting parallel to the ramp. The force can be found using the sine of the angle, specifically 100N * sin(25 degrees). There is some confusion regarding the calculations, particularly with the use of cosine instead of sine for the force component. The correct approach involves using the sine function to find the magnitude of the force acting down the ramp.

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...
