Consider a mixture of helium and neon at room temperature =(300k) both are monatomic and to a very good approximation ideal gasses. What is the typical speed of a helium atom ? Neon atom?
What about their individual( partial) pressure? Consider a head on collision between two such atoms that is one neon and another helium , and evaluate the velocities of atoms after the collision. What is the probability of the inverse process?
A planet of mass 6.00 1025 kg is in a circular orbit of radius 2.00 1011 m around a star. The star exerts a force on the planet of constant magnitude 5.03 1023 N. The speed of the planet is 4.09 104 m/s. All through this half "year", how much work is..
