*shakes head*You should have told which variant this is ._. It's definitely not 11
already added*shakes head*
I got two of the same mistakes as u.
The 480N one. And the GPE one. I chose GPE...
Here's my contribution anyhow:
...
Model of crane and real crane ratio...
i got the train one wrong and the graph and the momentum one my electricity part i think i got the graph one wrong some saying C some Dalready addedim confused now about the electricity ones...cant seem to recall anymore :/
which one is no 11 i cant remember now :?OK guys heres all the ones i remember, please DO add in any, i cant remember all 40, here we go! [P.S, ill be adding my answer to it as well]
1) unit of resistivity [I did B, m3A-2s-3]
2) line of action of force in the circle [i did C, apparently its B]
3) forces 1 vector 1 scalar [K.E and Force]
4) train and markers positioning one [600 m]
5) new proton/nucleon number after emission of alpha + beta particle [the option with 88 proton number]
6) mass of alpha particle [10^-26]
7) number of wavelengths of shortest wavelength in 1 meter [10^14]
8) temperature unusual scale [400C]
9) thermistor+LDR one where voltmeter reading would be judged [I did both low, apparently it was thermistor high heat, LDR low light]
10) momentum one which must be true for elastic collisions [speed of approach = speed of seperation]
11) ball rising steadily [i did GPE, i can not yet decide if it was energy is conserved or GPE]
12) air speed [480, apparently correct is 16000]
13) units of young modulus [Nm-2]
14) current distribution between P and Q [1/18]
15) force required to balance [0.29 Nm]
16) transverse wave always [polarized]
17) new wave over older smaller wave [333 frequency, 4 amplitude]
18) people in train and train moving with its own mass at an angle to gravity [i think it was C...cant remember options]
19) arrow and bow [14-19 meter, cant remember which it said]
20) graph of something that changes as ball bounces [displacement]
21) the scaled crane and object one [10^1, not sure though]
22) terminal V drops when switch closed [because of drop across R]
23) when resistance of variable resistor goes from 10 to 0 [graph drops of P decreasing to 0 from max]
24) person jumps from balloon [air resistance increasing non-uniformly before going flat]
what were the options? do u remember cause i still dont and it is the last one i doubt i already got 4-5 wrong :'(the one about ball rising while neglecting air resistance
Yeah... but I'm proud of myself for getting the 1/18 one right. (Assuming that's the correct answer!)already addedim confused now about the electricity ones...cant seem to recall anymore :/
you know, 70 kg people, 200 of them, 80,000 kg train, moving at 30 degree to horizontal...And I do NOT recall Q18...
o think i did the last one :/options were like, GPE rises uniformly with ascent, total momentum same, KE remains constant and total energy of system constant.
i got the crane one wrong i chose B :/ it was 10^2 acordingg to maj of peopleyou know, 70 kg people, 200 of them, 80,000 kg train, moving at 30 degree to horizontal...
I guess 5 down here.im pretty sure of that one. Right now i have circle, thermistor/LDR, air force, ball wrong. So -4 for me.
