AI Thread Summary
Conductors are materials that allow the flow of electric current, such as copper and aluminum. The stress-strain relationship describes how materials deform under stress, with examples including elastic and plastic deformation. Insulators, like rubber and glass, resist electrical flow, preventing current from passing through. Independent variables are those that can be manipulated in an experiment, while dependent variables are the outcomes measured in response to changes in the independent variables. Understanding these concepts is crucial for studying material properties and behavior in physics.

Find a library.
 
thanks for your help
 
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...
