Regarding Question 17, is it A or B? Shouldn't it be A since it's a linear expression?EMF does get induced, but there is no induced current
If 17 is A, then 20/20

It's not linear, its hyperbolicRegarding Question 17, is it A or B? Shouldn't it be A since it's a linear expression?

From memory B, because when you pair a couple of equations together Ek was inversely proportional to lambda...I'll put some working out..Regarding Question 17, is it A or B? Shouldn't it be A since it's a linear expression?

I'm looking at a graph of it on the Jacaranda book, and it's just a straight line.It's not linear, its hyperbolic
Yes but it's probably a graph with frequency in the x axis in this case we have wavelength in the x axis.I'm looking at a graph of it on the Jacaranda book, and it's just a straight line.
Good point hehe, I just thought it would be flipped over.That would be KEmax vs frequency
It was asking for KEmax vs wavelength
You assume thrust is constant.Seemed to me to be a toss up between B and C. Looking back at it now it's most likely B as it isn't always constant thrust...I'm a little curious about this one too.
?? Which MC was this?How did you answer the question with the satellite being slowed down?
I think he means question 20..?? Which MC was this?
oic, but was the constant thrust answering this guys q?I think he means question 20..
13 is A, Arsenic is type 5, therefore more free electronswhat's the answer for 13? I got B..
fahhh just realised that!!! I was looking at the oxygen group and saw arsenic on the group before it so I thought arsenic was in group 3... Exam pressure got me again.13 is A, Arsenic is type 5, therefore more free electrons
Woot, that means I got 20/2099.9% sure these answers are right, i went up to a phys teacher to confirm my answers were correct lol.
