Atoms can be "cooled" to incredibly low temperatures by letting them interact with a laser beam. various novel quantum phenomena appear at these temperatures.
what is the rms speed of cesium atoms that have been cooled to a temperature of 100nk ?
express your answer to two significant figures and include the appropriate units.
