Under secondary electron emission (see Problem 4.41), the energy distribution function `F (W_2)` for secondary electrons is represented sufficiently well by two curves `(1 and 2)` shown in the figure accompanying the problem. Which of the two curves represents the primary electrons and which, the "true" secondary electrons?

Which ofthe following curves may represent the energy of electron in hydrogen atom as a function of principal quantum number n:

The diagram shows the energy levels for an electron in a certain atom. Which transition shown represents the emission of photon with the most enegy ?

Following represents the Maxwell distribution curve for an ideal gas at two temperature T_(1) and T_(2) . Which of the following option(s) is/are true?

When a certain circuit consisting of a constanteuif, an inductance, and a resistance is closed, the current in it increases with time according to curve 1 (see the figure accompanying the problem). After one parumoter (G, L, or R) is changed, the increase in current follows curve 2 when the circuit is closed a second time. Which parameter was changed and in what direction?
