I got C for q4 as the ball is travelling at 8ms-1 so in 2s it would have travelled 16m. Which I think means that the distance is 16-3 = 13m

Either that or it was something to do with horizontal and vertical velocities

Alright, I'll update the post; that seems plausable to me, thanks for pointing that out.

Not 100% certain tbh but it’s the only thing that jumped out at me. No problem.

For 16 I got E, V1/T1 = V2/T2, I did 0.3/20 x 50 to get 0.75m^3. I might of done it wrong, how did you work out the answer to be 0.33m^3

You have to change the temp to kelvin

Just wondering if q11 is A
You said B but If the lamp is off why would it turn on when the light level increases? You don’t want a lamp to turn on when it’s bright so I think it would be the decreases one- eg when it’s dark.

My thinking was:

"There is a variable resistor and a light dependant resistor. I noticed the transistor, so wouldn't increasing the light level increase the voltage; hence increasing the voltage to be greater than 0.7V, therefore switching on the transistor, which lights the lamp. I might be wrong, but that's what I think. I'd need to see someone's working for it xD."

RobDob also said A, so I will change it the now; as I'm positive you guys are right :P

Fair enough. I guess we’ll have to wait and see in August :/
Seem to have about 18ish out of 25 so quite happy.
Can someone share their reasoning for q24? Thanks

Well I recognised that the ldr was on the bottom so was the decider and ruled out anything not to do with light and then thought it was A from logic.
I’m not very good at explaining, so hope you understand. Thanks
