    I just put A down
    good lad, i tended to go for D when i didnt have an answer

    2.7 mm without a shadow of doubt.it was 2mm on the large increment and it matched up on the 7th small increment on the vernier scale.

    its a mixed opinion , we need to ask a physics professional
    I'm not a physics professional but,

    If you use 4 resistors: 1/45 + 1/45 + 1/45 + 1/45 = 0.0889
    1/0.0889 = 11.25 Ohms resistance.

    The Voltage I think was 32V. Power = voltage^2/resistance.
    so 32^2/11.25 = 91W

    91W is less than 100W so is not quite using the maximum power, 5 resistors would be 114W which goes above the maximum power.

    Therefore 4 components maximum before maximum power reached.

    For the mass of a fuel decreasing, did people put A- less friction. I simply thought M1 mechanics here.
    I put C- Acceleration and deceleration is bigger- because F=ma, F from the engine stays constant, m mass decreases so acceleration increases (newtons law). I watch formula one and I thought that friction is good because the tyres work better when in the working window of a high temperature.

    I got 4 for my answer, but I did completely different way(completely random), would I still got full marks?

    For the mqc question about a girl jogging did anyone else get velocity = 0 and speed = 2.4 ??

    you might want to check around page 10/11.
    the debate is around the 2.7 - 2.9 mark, unless of course everyone else is blind

    it was random , like I used v=ir and then like I divides 100 by something to get 4.4.. ish and then I rounded it down and got 4. lol was just a guess wasn't expecting it to be right. would u just get full marks for the right answer or do u get method marks(fml)

    Girl runs as 2m/s for 30 seconds, turns around and runs for 20 seconds until she reaches original spot.

    2m/s x 30s = 60m, so she ran 60m forward.
    60m/20s = 3m/s so she was running at a speed of 3m/s on the way back.

    Average Velocity: [(2 x 30) + (-3 x 20)] / 50 = 0m/s
    Average speed : [(2 x 30) + (3 x 20)] / 50 = 2.4m/s

    So the answer for this question was "A".

    XD I think you'll probably get a mark for the correct answer, and another for using a formula, usually examiners just look for the answer. But I think you'll drop like 1 mark max.

    Not sure where u have got 50 from and why u are dividing by it. But the average speed is 2.5m/s. because (u+v)/ 2 is average so (3+2)/2 = 2.5 m/s

    Velocity is zero but average speed is 2.5 m/s

    I got around 277 but to be completely honest i had no idea what i was doing haha

    I did the same thing but I think it's wrong tbh

    This is wrong because theres no unifrom acceleration. 2.4 was correcr.

    that's what i thought. can someone confirm this?

    Thanks, I believe that as long as you get the right answer that all that matters. hope the examiner thinks like me
