Marbles of mass M = 12 grams = 0.012 kg are placed on the floor at room temperature (about 20° C = 293 K). They are in thermal equilibrium with their surroundings. What is a typical height above the floor for one of these marbles? (Mgy kBT)
T = 293 [K]
M = 0.012 [kg]
g = 9.81 [m/s^2]
y = (1.380x10^-23 [m^2*kg/s^2*K])*(293 [K])/((0.012 [kg])*(9.81 [m/s^2])) = 4.55x10^-20 [m]
