(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!

In an old-fashioned amusement park ride, passengers stand inside a 3.0-m-tall, 5.0-m-diameter hollow steel cylinder with their backs against the wall. the cylinder begins to rotate about a vertical axis. then the floor on which the passengers are standing suddenly drops away! if all goes well, the passengers will “stick” to the wall and not slide. clothing has a static coefficient of friction against steel in the range 0.60 to 1.0 and a kinetic coefficient in the range 0.40 to 0.70. part a what is the minimum rotational frequency, in rpm, for which the ride is safe? express your answer using two significant figures. f f = rpm
