Particle occupies a in a classical gas, the probability is negligible that more than one given single particle state. the mean occupation number of a single particle state s in which the particle has translational energy 8," is given by 3/2 h2 n |exp(-be,") v 2ttmkt (a) write down an and hence find its de broglie wavelength adb- expression for the momentum of a particle with translational energy [2 marks] (b) assuming that the mean translational kinetic energy of a molecule is kt , show that the condition for a classical gas is satisfied if adb < < l where l is the mean separation of the molecules. [6 marks] (c) why do you expect the condition adb < < l to correspond to the classical regime?

Groups of organs that work together to complete a process in the body are called: a. cells b. tissues c. nerves d. systems

During spring semester at mit, residents of the parallel buildings of the east campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. a balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. assume that the stretching of the hose obeys hooke's law with a spring constant of 89.0 n/m. if the hose is stretched by 5.80 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length? unitst 3 number-1497 the tolerance is +/-5% open show work click if you would like to show work for this question:

Unpolarized light of intensity so passes through two sheets of polarizing material whose transmission axes make an angle of 60∘ with each other as shown in the figure. what is the intensity of the transmitted beam, st?
