Homework Statement
In the Einstein model of a particular solid, one quantum of vibrational energy
is ΔE=0.050 eV. This means an energy equal to ΔE is needed to raise an oscillator from
one energy level to the next highest level. Assume this solid is at room temperature. What
is the...
Homework Statement
A planet has mass, 2 x 1022 kg, and radius, 2 x 106 m. Initially, its
atmosphere contains gas particles of various masses. If the gas is at temperature, 400 K,
and has a Maxwell-Boltzmann velocity distribution, what mass of particle will typically
escape from the...
