What is the rms speed of helium atoms when the temperature of the helium gas is 206.0 k? (possibly useful constants: the atomic mass of helium is 4.00 amu, the atomic mass unit is: 1 amu = 1.66x10-27 kg, boltzmann's constant is: kg = 1.38x1023 j/k.) submit answertries 0/20 what would be the rms speed, if the temperature of the helium gas was doubled?

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.
