Want to compare multiple-choice answers? (1 Viewer)

[Stopsign]

They may still be in your head but I want to compare them to what other people have thought. That's all. The multiple choice was quite easy.

 

[Riviet]

I have a bad memory when it comes to remembering multiple choice answers.

 

[Stopsign]

You still have the multiple choice papers and you might've circled them there.
Here are my first five:
1. C
2. B
3. D
4. B
5. D

I hope that I didn't make a fool out of myself but to me, they seem right.

 

[karoooh]

1. C
2. B
3. C
4. A
5. B
6. A
7. B
8. B
9. D
10. B
11. A
12. C
13. D
14. C
15. A

Don't know if they're right or wrong, haven't touched Physics since before trials, and I think these answers aren't too bad. So, someone: Hurry up and come dash my hopes.

 

[shinji]

1. c
2. b
3. d
4. b
5. d
6. a
7. c
8. a
9. b
10. b
11. a
12. c
13. d
14. c
15. a [the onli multi choice i guessed .. lol ]

 

[Ioup]

Can you post the multiple choice q's up please somehow.
I haven't got a copy.
Or at least describe one tricky multiple choice q and list the possible solutions and answer to it. It might jog my memory.

 

[Tbomb2k]

1.c
2.b
3.d
4.b
5.d
6.a
7.d
8.b
9.b?
10.d?
11.a
12.c
13.d
14.a (fuk i bombed this- damn calculator said it was E=10000V (double) typed it in wrong)
15.a

I think i might have got a few wrong... but this was the best i could do

 

[Stopsign]

Someone told me that 8 A is wrong. It could be B. I think he means that no flux was cut at the start.

 

[shinji]

q. 15:
emr is shined on metals .. photoelectrons are emitted.
blah blah blah
graph of frequency and maximum kinetic energy with different metals.
Emr has wavelength of 187nm which shines on an unknown metal. max kinetic energy of photoelectrons = 2.5 eV

based on this info, what is the unknown metal?
a. : Al
b. : Be
c. : Ca
d. : Fe

15. a [the onli multi choice i guessed .. lol ]

haha mate well you guessed correctly. i noe that's the right answer

 

[shinji]

Someone told me that 8 A is wrong. It could be B. I think he means that no flux was cut at the start.

but isn't it perpendicular to magnetic field?
hence, it starts off with max flux [sin@] and then decreases to 0 as it is parallel .. and yeah.

that's what it thought ~_~

 

[Lockhart]

1.C
2.B
3.D
4.B
5.D
6.A
7.D
8.B
9.A
10.D
11.A
12.C
13.D
14.C
15.B (think i got this one wrong)

 

[Riviet]

Looking at all your answers, I can conclude that I got about 12-13/15 (minimum)

 

[shinji]

haha mate well you guessed correctly. i noe that's the right answer

omfg. muhahaah

<3.
thanks to eeny meeny mino moe! bahahah i was opting for b ... but yeah. lol

 

[timkaldor]

1. C
2. B
3. D ?
4. B
5. D
6. A ?
7. D
8. C
9. A
10. A
11. A
12. C
13. D
14. C
15. A

Im pretty confident about all of these tell me any you disagree with

 

[Tbomb2k]

but isn't it perpendicular to magnetic field?
hence, it starts off with max flux [sin@] and then decreases to 0 as it is parallel .. and yeah.

that's what it thought ~_~

It's torque so it's cos@ therfore at right angle, which it is cos90 is zero, therefore zero flux. so 8 should be 'b'. is that right?

 

[Tbomb2k]

no.9 is not consistant enough. anyone got a definitive answer for this with justification? it is confusing.

 

[gamecw]

1c
2b
3d
4b
5d
6a
7d
8a
9d (not sure)
10d
11a
12c
13d
14c
15a

im pretty sure i got the rest right.. i cant believe i used 'time dilation' for length contraction at the end of 1st section..

 

[shinji]

yay another person who got 8. a .. lol

i made n educated gues at 9

how did u work out 15?

also i disagree with #7 .. i think it 's c. lol

 

[timkaldor]

for no. 9 i thought of Lenz's law and i didnt think any current would be produced just eddy currents in the disc
