(Sorry, this is a repost cause a spammer answered my last one). This is actually a question regarding Earth and Space Sciences!
I'm doing an online lab involving chance among 100 cubes. Since it's online, I don't have anyone to fully explain this stuff in-depth to me so I'd appreciate any and all help!
It mentions describing patterns and trends "in your graphs of the half-life" and it mentions "What is the half-life of the element Lokium?". A later question also asks about "Which trial did you reach the half-life of Lokium?"
I'm not sure what it means by half-life and what Lokium is or what it has to do with this assignment. Any explanation will be a great help!
I don't need answers, I just need some help to push me in the right direction! Thanks!

What is the weight of a feather (mass = 0.0001 kg) that floats through earth's and the moon's atmospheres?

Find the steady-state temperature at the center of the plate = /2, = /2) for sums of w from n=1 to n=19 (only odd values). find the value of n for which the change in /2, /2) is less than 1% from the value at the previous n. at this point, we consider the solution converged. does the value of the temperature at the center seem reasonable? in this part, the values of x and y are constant scalar values. you should produce a plot of the value of n on the horizontal and the estimate of the temperature at the center of the plate on the vertical. b. using the value of n (or larger) that resulted in convergence in part (a), create a contourf plot of the temperature distribution across the entire plate. use enough spatial subdivisions to create a useful plot. comment on the results. hint: you need to determine what “x” and “y” values to use to make your t matrix. i recommend using a different number of x and y values. use enough x and y values so that the plot is “smooth”.
