The distance from earth to a distant planet is approximately 9 x 107 km. assume that the frame size is 16 kb and the speed of light is 3 108 m/s. assume that the bit rate is 20 mbps.

plot the efficiency versus the distance when the bit rate is set to 20 mbps. discuss this plot.

In 1995 a research group led by eric cornell and carl wiemann at the university of colorado successfully cooled rubidium atoms to the 20-200 nk temperature range. assuming (incorrectly) that the rubidium atoms behave liké particles of a classical ideal gas, calculate the rms speed of a rubidium atom at a temperature of 112.0 nk. in the experiments one particular isotope of rubidium was used, rubidium-87. the molar mass of this isotope is 86.91 q/mol. tries 0/20 submit answer

If you touch a hot light bulb and get burned, that is an example of a. radiation b. convection c. conduction
