Mirror Lab One air inhalation hazard I observed during the Mirror Lab tour was for rhodite 906. In a large open room and workspace‚ the mirror lab utilized rhodite frequently to polish large new mirrors. This is concerning because this is a hazardous dust particle with its particle size at about 1.5 micrometers. The movement of these particles are heighted by water mist placed above the mirror to keep the rhodite from solidifying. The employees also sprayed down the mirror frequently which further

Physics Domino Lab I. Problem: What spacing between the Domino’s will provide the fastest velocity for a line of falling Domino’s. II. Background: The Domino C.I.M. lab that we have been assigned brings forth the question of the compression of a line of Domino’s. The question is‚ what set up of Domino’s has the fastest compression time. We intend on testing this by lining up different strings of Domino’s and finding which variable of distance has the greatest compression velocity
