How fast (in rpm) must a centrifuge rotate if a particle 9.00 cm from the axis of rotation is to experience an acceleration of 121000 g's? If the answer has 4 digits or more, enter it without commas, e.g. 13500.
Homework Answers
Centrifugal acceleration is given by the formula
a = w2 × r
r = 9 cm = 0.09m
a = 121000 × 9.8 m/s2= 1185800 m/s2
Hence, w = 1147 rad/s = 10961 rpm

1. A red photon has a wavelength of 660 nm. How fast must a star be moving toward the Earth for a red photon emitted by the star to change its color to an orange photon of wavelength 620 nm? You may, if you wish, express your answer either in m/s or in terms of the speed of light c (e.g., "0.021c"). [You'll need to do a little bit of algebra. Keep in mind that, by convention, the velocity...
