Numerically evaluate the following quantities
a) The probability that the 1s electron in the hydrogen atom is found in the tunneling (classically forbidden) region.
b) The probability that the 1s electron in the Ne+9 is found in the tunneling region. By this measure, is a 1s electron in Ne+9 more or less "classical" than in a hydrogen atom?
c) The probability that a 10s electron in the hydrogen atom is found in the tunneling region. Again, by this measure alone, is a 10s electron more or less "classical" than a 1s electron? If your coding works for a 20s electron, find the tunneling probability for that case too. Do you see a pattern here?
d) The probability that an electron in the hydrogen atom with n=10 and l=9, is found in the tunneling region
Carbon dioxide gas enters a pipe at 3 MPa and 500 K at a rate of 2 kg/s. CO2 is cooled at constant pressure as it flows in the pipe and the temperature of CO2 drops to 450 K at the exit.
the first cash folw of a 25- year series of quarterly cash flows is equal to 35000. each cash folw in the series
Air enters the evaporator section of an air-conditioner at 100 kPa, 27oC with a volumetric flow rate of 6 m^3/min. R-134a enters the evaporator at 120 kPa with a quality of 0.3 and rate of 2kg/min and it leaves as a saturated vapor at the same pressu..
