A block of mass m attached to the end of a spring of spring constant undergoes simple harmonic motion with amplitude and angular frequency . The position of the block is described by a cosine function with an initial phase angle phi=0. Suppose that each of the variables m,,, and phi is increased in value.
1. Classify which increases produce an increase in the frequency of oscillation and which do not. Increases frequency Does not increase frequencyOptions:a. increase Ab. increase kc. increase md. increase phi

Hunter is in lab. he clears a spot on his lab bench to start working. he also puts his lab coat and goggles on. he then identifies where all of the safety equipment is. he notices his station is next to the fume hood, which ventilates the chemicals stored there. the noise of the fume hood was bothersome, so hunter turned it off. which could be an error in his set-up? he should not turn off the fume hood.  he should wait to put on his coat until after the directions are given.  he should wait to put on his goggles until after the directions are given.  he should not sit next to the fume hood.
