AI Thread Summary
Photocells offer several advantages, including energy efficiency, automatic operation, and reduced electricity costs. However, they also have disadvantages such as sensitivity to environmental conditions and potential malfunctions. Important characteristics to consider include response time, durability, and light sensitivity. Assessing advantages and disadvantages often depends on specific applications and user needs. Understanding these factors is crucial for effective implementation of photocells.

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...
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 .
