and 18/20 for math, again I blame english for the 2 wrong in the maths since I didnt know the words...

well I knew that the y/g wire is ground so it was 50/50 - I lost 😀
 
8/10. Newton question tricked me (duh!) and the british wiring color coding was unfair, so IMO, 8/9.
 
10/10. Come on guys, these are all questions for ~15yr olds.

Shame on all of you who didn't know how to wire a plug. Hand in your man cards pronto.

Only compression waves, like sound, oscillate longitudinally.


Besides, It called Frequency Modulation because you changethe Frequency to change the channel. The frequency does not occilate while listening to a specific station.

Meh - I've never seen a piece of nomex with a blue wire in it. How is it physics anyway?

BULL! We americans should be exempt from that question.

In the US, Red = + Black = -, 3rd color = ground (green or white are common)

Well that depends on who built the suit.

Ok y'all probably are lost that is a typo they meant Romex as in the general cable brand name for non metallic sheathed cable commonly used in homes.

Nomex is a heat resistant material used in racing gear for example...

Yes it really is not physics. Lot of tests will have these kinds of questions though. Lots of tests are poorly written too. Too bad the youngin's are striving on learning how to take the test rather than learn the fundamentals that should be learned eh?

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.


i agree completely...that's electrician stuff. But I worked on some equipment that was made in a european country (Germany mostly) some I am familiar with ISO wiring standards.
 
wtf number two doesn't work. They ask for weight so therefore, the answer would be in kg. If they asked for force, then it would be in newtons. It's that bloody simple, don't give any crap about how 9.81 /= 10 so the answer is just somehow obviously not kg

kg = mass of object

weight = force of gravity on object

no. weight is not measure in kg. Kilograms is the SI unit of measurement for mass NOT weight. weight is the formal term for the strength of the force of the earth's gravity (or some other planet) that acts upon the object.

ie. weight can be many different values for the same object depending on where you are, but mass is always the same (EDIT: unless of course the object is moving, then it has increased mass- due to the theory of relativity... but for the most part, yes mass is same).

Is it considered inappropriate if I call my physics teacher a mxxxxxxxxxxxg liar who has dammed himself to hell?
