Optics

Just had a theoretical doubt. Suppose there is a concave mirror. If we break that mirror from its pole, there will be 2 identixal type of mirrors. What would be their principal axis?

MOT

bruh, here we took N2 which has like 14e. so in MOT, for total e < 14, we consider or believe that pi 2px and pi 2py have lower energy than sigma 2pz so like my doubt is when we fill the electrons, we follow the hund's rule and aufbau principle, so like if a molecule has 10 electrons, as per what i have learnt is that when we start filling, we fill the lower energy orbitals first but since we have only 10 electrona, pi 2px and pi 2py will get occupied first so this means that pi bond is established before sigma, how? or am i misinterpreting the ENTIRE MOT...

Thermodynamics

so in part 2 of this question i wasnt able to solve it at first. now the solution is the second image i have attached. why is Pext taken to be 1? sorry if its obvious (my guess is that the final pressure is 1 atm?) but i dont get it/need to confirm. (source : dexterchem's lec 3 on thermo)
