Homework Answers
Answer #1
Polarimeter is an instrument used to determine the optical rotation of chemical molecules when plane polarised light will pass through a chemical molecule, the angle of rotation changes ie, it may rotate clockwise or anti clockwise direction. Molecules which rotate the plane polarised in a clockwise direction are called dextrorotatory and which rotate it towards anti-clockwise are called leavo rotatory. Molecules which rotate the plane polarised in a clockwise direction are called dextrorotatory and which rotate it towards anti-clockwise are called leavo rotatory.

A centrifuge is rotating at 4700 RPM in a clockwise direction
when the power is turned off. It slows to a stop in 63 seconds. In
a coordinate system where the rotation is occurring in the x, y
plane and the z-axis points up away from the table,
a) What angular acceleration does the centrifuge experience while
slowing down? (Assume constant acceleration and pay attention to
the sign.) [ , , ]
rad/s2
