Physics: How smart are you?

Ionization detectors use 1 microcurie of Americium-241 that emits alpha particles.
Photoelectric detectors use a gallium arsenide light emitting diode at 940 nanometers for simple detection.

So the way the question was phrased, alpha and IR are correct answers.

woohoo 10/10 then!

7/10

The wiring question and the smoke detector, and the question with the transformer screwed me.

Doesn't FM have a longitudinal component? It's frequency is modulating so it is oscillating longitudinally as well isn't it?

Only compression waves, like sound, oscillate longitudinally.

in US of A, black is live, white is neutral, and green is of course earth

9/10, not familiar with the UK's wiring scheme.

20/20 on the English quiz.

17/20 on the 'Maths' quiz, but it took me too long to figure out a few of the problems, hehe.

Took physics, didn't care about it and forget it all when I entered the working world.

 

[Mojoed]

7/10 here too. :thumbsdown:

The wiring question isn't physics - it's simply convention, and apparently not the same convention everywhere. Around here Live is black or red, neutral is white, ground is green or bare.

5, no physics for 5 years

I missed the wiring question, which is based on the british system. I also missed the question on longitudinal waves.

Same here.

What the hell is a wiring question doing on a physics test anyway?

My distance in Newtons to the center of a Proton, in calories, has nothing to do with how many volts are generated when I think of a picture of a smoke detector with a fresh battery inside it.

Physics sucks ass.

 

[AbAbber2k]

Wow I suck at physics. I was never big on science though. Chemistry was fun, but my best grades were always in literature and more abstract thinking classes.

 

[bootymac]

9/10, got the wiring question wrong. Doh

Haha, literature is more abstract than any of the natural sciences?

WTH does knowing the color of wires have to do with Physics?

 

[Triumph]

The color of electrical outlets has nothing to do with physics. 9/10.

 

[meltdown75]

maybe the Mrs. will try it later.

she's like fskcin Einstein man, it's SICK

 

[dullard]

Really stupid questions there.
[*]What do planet names have to to with physics? This isn't astronomy.
[*]Wire colors in England aren't the same everywhere in the world. Heck, for the most part there aren't wire color standards. I've wasted far too much time searching for color standards which don't exist for some of my experimental machines. There are suggestions and historical conventions, but for the most part there are no color standards.
[*]I thought there were two types of smoke detectors.

 

[phreakah]

4/10... im studying business though

 

[Mardeth]

5/10, but I blame english (and the beers)!

 

[Jzero]

I got the wiring and smoke dectector questions wrong, although I stand by my answer for the smoke detector question, as there are iR smoke detectors.

I also got two other questions wrong, not because I suck at physics, but because I suck at arithmetic and didn't feel like using the calculator.

 

[BurnItDwn]

9/10 .... pretty crappy ohh well.

i never took physics and guessed on most of them

Same score...
