Review Drill #3

1	Given two pulleys are rotating in unison because a common belt passes over their rims, which value is the same for both pulleys: their tangential velocity or their angular velocity?
2	Given two specks of dust are on a common rotating record's surface, which value is the same for both: their tangential velocity or their angular velocity?
3	What force supplies the centripetal force to keep the specks of dust on the record's surface as it rotates?
4	At what points in a spring/pendulum's oscillation is the its velocity maximum?
5	At what points in a spring/pendulum's oscillation is the its acceleration maximum?
6	In thin film interference, when are reflections out-of-phase with the incident beam?
7	If both a 40 Watt light bulb and a 100 Watt bulb are plugged into identical 120 volt outlets, which one has the thicker filament?
