A rotating wheel requires a time Δt = [01] to rotate 37.0 revolutions. Its angular speed at the end of the interval is ω = 75.9 rad/s. What is the constant angular acceleration (rad/s2 ) of the wheel

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
