EDEXCEL A2 Physics EXAM Unit 4 Physics On The Move 20th June 2016 (NOT I-A-L)

I thought I didn't round but got 20.5m, did you use exact values in your calc?

No no no, no no no. It was D. All my teachers said D

Question 3 was obviously D, Newtons aren't mass, can't believe you all got that wrong lol. My teacher said it was D too lol

That's most likely because you told your teachers that option D was just newtons when there were other units too

No no no, no no no. It was D. All my teachers said D

My teacher also said this, spot on mate.

Your teacher is wrong

No no no, no no no. It was D. All my teachers said D

He's my dad aswell actually I dont think my dad would lie to his son lol

No no no, no no no. It was D. All my teachers said D

No no no I told them Nm-1s2

He's just messing with us. Your telling me MeV is a unit of mass???

V isn't constant, in fact, V is reduced when the tire is not inflated properly. It would overestimate the speed, but not because the frequency of emf pulses is greater, rather because of the calibration of the device.

Yes the speed does change, but at any given speed the frequency of rotation is higher than what the device would be expecting for that speed.

For the question to do with that capitactor charge question.

If I did everything right but wrote down mm = x10^-6 instead of x10^-3 how many marks would I get?

probably 0 i think i did the same buddy. Spot on.

I think the question asking for "max decrease" implies that you can either increase or decrease from the starting point. If you use 2.8mm to find your starting point, you're already at the max so you can't increase further, therefore 3.5mm must be the 'starting point'.
