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).

answer: good job it's all correct !

explanation:

the bal will not change its velocity.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
