AI Thread Summary
The resistance of a wire is determined by its length and resistivity, with the given wire having a resistance of 0.4 Ohms per meter. For a 50-meter length of this wire, the total resistance would be 20 Ohms. There is confusion regarding the terms "resistance" and "resistivity," with resistance being the measure of opposition to current flow, while resistivity is a material property. The discussion also raises questions about the resistance of a 1-meter wire, which would be 0.4 Ohms. Clarifying these concepts is essential for accurately solving resistance problems.

The resistance of a certain type of wire is listed as .4 Ohms/meter. What is the resistance if 50 meaters of the wire?

R=(.4 Ohms/meter)*(50 m) / Area

what is the area?

how do I solve this?

You are confusing the given information with "resistivity".

If the wire has a resistance of 0.4 Ohms per meter, what would the resistance of a 1 meter long wire? And what about the resistance of a 50 meter wire?
 
maybe the resistivity is 0.4 ohm meters
 
what is ohms per meter a measure of?
 

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...
