How can horizontal force affect power in scientific experiments?

AI Thread Summary
Horizontal force plays a significant role in scientific experiments, particularly in understanding how it affects power output. The discussion emphasizes the importance of showing detailed work to validate answers rather than simply questioning their correctness. Participants encourage a collaborative approach to problem-solving, where individuals can present their calculations for review. The insistence on providing evidence for claims reinforces the need for accuracy in scientific inquiry. Engaging in this manner helps clarify misunderstandings and fosters a deeper comprehension of the concepts involved.

Welcome to the PF.

We don't solve your homework for you. Rather, please show us your work in detail, how you arrived at those answers, and we can check your work for you.
 
The so called "correct" answers are correct. If you got something else, please show your work.
 
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...
