Yeah, 0.39 from part two its e^-ux -
[HELP] Physics P42
Good luck! Part b is almost all about memorizing, memorize everything and you can get a full mark on it. -

It is correct, since E=hc/lambda The larger lambda, the less energy. -

We know that alpha( the intensity reflection coefficient ) is also = Ir/I We need Ir We got alpha in first part 0.33. From second part, I2=Ie^-ux But since it's received back at the surface, it travelled twice the thickness, so it's 2x now. So Ir= apha(I2)=0.33(0.39^2)(I) This is why we square... -

Could someone just give me a quick explanation with tips on how I should find the area under a graph when I'm asked to do so? Do I count the squares? Then what? Thank you -

The width depends on where Vin is 0, so everytime the graph of Vin is 0 you switch the polarity :) try sketching it and upload it here so I check how you sketched it -

Here are some important questions from O/N 2013 p32 which I felt need to be posted here :) Also, I have this doubt, Q8)b) how do we find the Least |z-w| for the loci? It carries two marks :/ , I tried to do it but it's not working :/ Help would be very appreciated for my doubt :) -

Just draw half rectangles with their heights at +5v and -5v since it can never exceed the supply. Each time, draw the half rectangle opposite to the vin , if the cycle of vin is +ve, draw vout at -ve and vice versa -

The Eqn KE= 3/2(k)(T) is for a single molecule only, you need the change in KE of all the molecules. So Total KE change = 3/2(1.38 x 10^-23)(460-280) (6.023 x10^23)= 2240 J We multiplied by Na(Avogadro's number) because there is 1 mol of the gas, so there is this much molecules.
