Solving schrodinger's wave equation for a hydrogen atom, we obtain the lowest energy state when n = 1,1 = 0, and m = 0, the corresponding wave function of the electron is given by 4. 100-jna0 where ao = mog? the radial probability density function pni(r), or the probability of finding the electron at a particular distance from the nucleus, is 4πτ2(ψ100 plot the probability density function pa(r) as a function of r/ao . proof that the most probable distance from the nucleus is the same as that predicted by bohr's model a. b.

The heater element of a 120 v toaster is a 5.4 m length of nichrome wire, whose diameter is 0.48 mm. the resistivity of nichrome at the operating temperature of the toaster is 1.3 × 10-6 ω·m. the toaster is operated at a voltage of 120 v. (a) what is the power drawn by the toaster? (b) if the cost of electricity is 12 ¢ per kilowatt-hour, and it takes 2 minutes to toast bread, how much does it cost for toasted bread? (c) when the heater element is at room temperature, is the resistivity in the nichrome wire greater than, less than, or equal to it’s resistivity when at operating temperature? explain.
