AI Thread Summary

To calculate the RMS speed of nitrogen at 227°C, the ideal gas law and the formula for RMS speed, v_rms = √(3kT/m), can be utilized. The density of nitrogen at standard temperature and pressure (STP) is provided as 1.25 kg/m³, which can help determine the molar mass and subsequently the RMS speed. The temperature must be converted to Kelvin for accurate calculations. Using these principles, the RMS speed can be calculated effectively. Understanding these equations is crucial for solving the problem.

Hiya,

Im having trouble answering this question.

If the density of nitrogen at STP (1.01 X 10^5 Pa and 0 degrees celsius) is 1.25kgm^-3, calculate the RMS speed of nitrogen at 227 degrees celsius.

Could someone please point me in the right direction?

Thank you.

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 '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...
