The Speed of Light and the Moons of Jupiter Introduction: In this lab we focused on the eclipses of the moon Io of Jupiter. Galileo was the first to discover the four moons of Jupiter and since then astronomers have discovered the orbital periods of them‚ 1.8 days being approximately Io’s. It was also noted that these moons disappeared and reappeared at certain points in their orbit. This was because when the moons were behind Jupiter they were not able to reflect light. In this lab we had

Accordingly‚ Tough elaborates on the coding speed- test‚ which was conducted by Carmit Segal‚ a professor at the University of Zurich. He presents an overview of the study‚ by which he states‚ “First‚ participants are given an answer key in which a variety of simple words are each assigned a four-digit identifying number … a multiple choice test that offers five four-digit numbers as potential correct answer for each word … All you have to do is find the right number from the key above and then check that
