The discussion revolves around the mathematical modeling of rabbit population growth, specifically how the birth rate relates to the population size. It highlights confusion regarding the equation N=2N and the conditions under which N becomes 3N. Participants express a need for clarification on the population dynamics over time. The conversation indicates a misunderstanding of the exponential growth model in relation to time intervals. Clearer explanations and examples are requested to resolve the confusion.

Rabit bith rate is ~1/N which N is rabit population, after 2 hours, N=2N but after how many hours N=3N ?
thank you
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...
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 .
