AI Thread Summary

Stoke's Law describes the settling velocity of spherical particles in a fluid, stating that the velocity is proportional to the square of the particle radius and the difference in density between the particle and the fluid. In a hydrometer test, Stoke's Law is applied to determine the specific gravity of soil particles by measuring the depth to which a hydrometer sinks in a soil-water suspension. This method allows for the assessment of particle size distribution and soil classification. Accurate measurements depend on factors such as fluid viscosity and temperature, which must be controlled during the test. Understanding Stoke's Law is essential for interpreting hydrometer test results effectively.

How about YOU give a brief overview of Stoke's Law and it's application in a hydrometer test? It's your homeowrk. If you have specific questions, ask away. We will not provide a book report for you.

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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...

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 .
