AI Thread Summary
The discussion centers around a challenging problem involving a spring scale that can only weigh up to 25 KG, with participants tasked to find a way to determine the weight of an object exceeding that limit without using any scales or spring-related tools. Clarification is requested on the restrictions against using the provided spring scale. Participants are encouraged to think creatively and suggest common objects for potential solutions. The conversation hints at the possibility of simple, practical answers that do not involve complex or unconventional methods. The challenge emphasizes critical thinking and resourcefulness in problem-solving.

Okay here is the 1 million dollar 100 bonus mark question...

If you have spring scale that can ONLY weighs no more than 25 KG. You have a mass that is MORE than 25 KG. How can you figure out the weight NOT using ANY SPRINGS, SCALES, OR ANYTHING ASSOCIATED WITH SPRINGS AND SCALES. Items MUST be common objects. (answer can't be too "wild")

a bit more clarification on " NOT using ANY SPRINGS, SCALES" would be nice.

could you still use the spring scale you're already given.

There are lots of easy answers. Perhaps you could come up with some yourself.
 
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 .
