Normal body temperature is about 307k. an infrared detector which measures the power per area (r = p/a, where r=sigma*t^4) radiated from a small section of skin is sensitive to variations in r of 1%. what temperature difference can be detected?

The differences between  a compression wave and a transverse wave?

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
