AI Thread Summary
To find the ratio of wave speeds (VA/VB) for two steel guitar strings with different diameters and tensions, the relevant equation is v = √(T/μ), where T is tension and μ is mass per unit length. String A has a tension of 410.0 N and a diameter of 0.50 mm, while String B has a tension of 820.0 N and a diameter of 1.0 mm. The mass per unit length is affected by the diameter, with String B having a greater mass per unit length due to its larger diameter. By substituting the values into the equation, the ratio of wave speeds can be calculated. Understanding these relationships is crucial for solving the problem effectively.

Homework Statement


Two steel guitar strings have the same length. String A has a diameter of 0.50 mm and is under 410.0 N of tension. String B has a diameter of 1.0 mm and is under a tension of 820.0 N. Find the ration of the wave speeds, VA / VB
in these two strings.

Homework Equations


V= ƒ λ
FT = FG

Amongst your standard equations, you should have one that relates wave speed in a string/wire to tension and mass per unit length.

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...
