A block of mass m = 5.9 kg slides from left to right across a frictionless surface with a speed It collides with a block of mass M that is at rest. After the collision, the 5.9-kg block reverses direction, and its new speed is The block of mass M travels to the right at a speed V of 3.8 m/s. What is M? 7.9 kg

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

What are the theoretical properties of a gas at a temperature of 0 kelvin?
