What is the weight of a radioactive sample with a given half-life and activity?

AI Thread Summary
To determine the weight of a radioactive sample of 59Fe with a half-life of 44.496 days and an activity of 1000 disintegrations per minute, one must use the relationship between half-life, activity, and mass. The activity indicates the number of disintegrations occurring, which correlates to the amount of radioactive material present. A larger mass results in a higher activity rate, as more atoms are available to decay. Calculating the weight involves using the decay constant derived from the half-life and applying it to the activity formula. Understanding these relationships is crucial for solving the problem effectively.

You are given the half-life and also how many disintegrations per minute are occurring with this sample. The more massive the sample, the more disintegrations per minute there will be...
 

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...
