AI Thread Summary
The discussion revolves around preparing for a test by working through past exam papers, specifically focusing on a problem related to waveform sampling. The user has calculated the time for one complete cycle as 50 microseconds and the frequency as 20,000Hz but is struggling with the last question. Clarification is provided that the problem asks for the information transmission rate based on the sampling period of 1.0 microsecond. The key takeaway is that the sampling frequency can be derived from the given sample period. Understanding these concepts is crucial for effective test preparation.

I'm doing some past exam papers to revise for my test on thursday. And I can't work out the last question in this problem.

I worked out the time for one complete cylce is 50 microseconds, and the frequency is 20,000Hz, 1/Time period. I can't work out the last bit though.

I think they are just asking for the sample rate, which is related to the sample period, which they give you. Not sure if it's any more compilcated than that...
 
so its 8bits s-1?

No. The problem says, "The waveform is sampled every 1.0us", and then asks for the corresponding information transmission rate or something. The wording is a bit off, but I think they just want to know the frequency of the waveform sampling, which you get from the 1us period number.
 

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...
