DEFINITION 38 adding water shortens the column of moving air inside the bottle, thus increasing its frequency (pitch) TERM 39 how is a drums pitch related to its fundamental pitch? DEFINITION 39 its not! TERM 40 The amplitude of each mode on a drum depends on.. DEFINITION 40 how hard you hit the drum and where
an objects natural vibration or resonant frequency is determined by its mass size and shape stiffness (elastic nature) and composition TERM 47 the frequency of vibration (pitch) is proportional to _____ and inversely proportional to...

There is an overall net electrostatic attraction
paper in a printing press can accumulate static charge, how does this happen? contact between dissimilar surfaces produces a charge on the paper, which carries that charge with it to isolated parts of the press TERM 62 basic solution to static charge is ____ DEFINITION 62 mobility TERM 63 since charge movement eliminates static electricity, ______ cause static electricity DEFINITION 63 insulators TERM 64 moist air _____ static electricity b/c..
