Did anyone do this one?? How did you find it??
Question 1 was nasty. The one about the mean squre spped got me. I know what root mean square speed is but i don't get why it would be different for molecules of two different gases atthe same temp.
Too much writing!!!! >.< ((The momentum ones were horrible))
The only question that was OK was the motion under gravity one.
To answer that, i put different gasses have different masses, if the temp is the same, then they will have the same KE, that means that if the mass is higher in one, the speed will be lower.
I wrote that mean square spped depends on mass and kinetic eergy. It might get a mark.
the whole paper wasn't horrible, it was allright, each one of the question was easy and the whole school had the same opinion and even my teacher was saying that it was easy and the grade boundaries might be high. In my opinion they were all easy but it was a bit more theoretical than previous years, although its my first time, the test was quite easy.
I thought it was rather straightforward, I'd have preferred less writing questions.
who got an answer to the question about temperature change as 4, that one was one of the easiest
I got 4 exactly, and so did most of the people I talked to. What everyone get for the dart question? I got 8.something at angle of 17 degrees to the horizontal (or something similar).
for the dart question i got the first part for time 0.250 sec (3 sig fig) and then with the question about the magnitude and angle i got something like 13. summit and then my angle was 51.3 degrees because i did tan-1 10/8. since it is 10 is the opposite and 8 is the adjacent u need to use TOA.
