Calculate the mean free path of a sputtered atom in an ar glow discharge at 10 mtorr pressure. if the cathode-to-substrate spacing is 5cm, how many gas-phase collisions is a sputtered atom likely to encounter as it traverses this distance? kt / (21/2.d2-p), where d is the collision diameter of the molecule: -0.4nm for most molecules and a has cm unit

What is the speed of an object at a given moment?

Awave with a frequency of 500 hz is traveling at a speed of 100 m/s. what is the wavelength?

Listed below are the measured radiation absorption rates (in w/kg) corresponding to 11 cell phones. use the given data to construct a boxplot and identify the 5-number summary. 1.16 0.85 0.69 0.75 0.95 0.93 1.18 1.17 1.42 0.54 0.57 the 5-number summary is nothing, nothing, nothing, nothing, and nothing, all in w/kg. (use ascending order. type integers or decimals. do not round.)
