CONFIRMED mc answers! (3 Viewers)

u might be right, but most ppl in my school put 15d (ie 4 out of the top 5)

oh, i had no idea the top 5 at ur school wrote d. the answer must be it then

Question 12 is definitely a) Cathode rays can turn a paddle wheel.
And i'm question 15 is b) since conduction only occurs in the valence band in silicon doped with boron - P-TYPE doping

RE: 12, yes they can, but that doesn't prove they are charged particles. Only B only proved they are charged particles.

12 is b , it asked for what observation resolved the debate, th emain debate occured with hertz saying they werent deflected by electric fields but thomason eventually disproved this...

ives apparently we got 12 wrong.. didn't read the question properly argh how annoying! cos it says what closed the debate between CHARGED particles or em waves - apparently if we put paddle wheel that just proved particle, whereas electric proved charged particle

Part of the debate was that they did turn a padel wheel, and also were deflected by a magentic field. This was the first set of evidence that was argued over.

Several other experiments added more support to the particle theory, a major one was that they werent deflected by electric field before. But it was later proved they could be.

oh, gay. i didn't even read the other options when i was rushing through :burn:

12 isnt a.... onli magnetic or electric field shows charged

kk point taken.

 

[pdoueihi]

kk point taken.

lol are you sure you got the point? its b not a...
lol jokes read the first 4 posts "question 4 is A not C!!!!!" hate when ppl do that

 

[Batesy27]

did any one else put 5 a - this is what i got wheni put tv as the dilated time on the spaceship and to as the time on earth

yeah, k but didn't the magnets in the cathode ray tube already show that it was a charged particle.. except the wave-supporting physicists just wouldn't give up.

so then when the cathode turned the paddle wheel, it was basically a confirmation no only of the fact that cathodes r particles, but also that they are charged (as per the magnetic field experiment)

maybe u got t and t0 mixed up i think. coz time gets dialated on the cratf it will be slower for earth

lol i like that logic but since the particle theory guys didnt agree, it didnt "end the debate" i think

yer i think ur right bugger

 

[pdoueihi]

yer i think ur right bugger

i hate when they mixem up to try confuse u with the wording

 

[Aaron.Judd]

I got 13/15 then.

 

[Aaron.Judd]

I got no. 2 and no. 4 wrong.

 

[hamzie]

4 is def. c

 

[pdoueihi]

i got 13 as well provided that 15 is D not B. if its B then i got 12

 

[dolbinau]

What did you get 15? It's still disputed, hehe.

I got no. 2 and no. 4 wrong.
