A turntable rotates counterclockwise at 62 rpm. A speck of dust on the turntable is at ϴ = 0.37 rad at t = 0 s. What is the angular position, in degrees, of the speck at t = 10.0 s? Enter just the numerical value to three significant figures. This is NOT asking for the total angular distance traveled by the speck of dust, but for the angular position. That means if something starts at 0 degrees and does three complete revolutions plus 1 degree, its position is 1 degree, NOT 1081 degrees (3x360=1080).

Scientist have use computer models to create a series of maps that show how susceptible coastal cities in island countries are to the sea rising at different levels.the map shows that a 1 meter rise would swap cities all along the us eastern seaboard. a 6-meter sea level rise with sub merge a large part of florida. thermal expansion has already raise the oceans 10 to 20 centimeters the most likely cause,directly and indirectly, for such a rise in sea level is
