First 82.5 so I should not be correcting anybody, but…
That’s a common sense answer, you don’t die when you pick up a D-Cell for the same reason.
I don’t think it matters either way. The sensation of hot and cold is not a measure of temperature, but of rate of heat loss/gain, which depends strongly on thermal conductivity of the object.
I got 97.5%, by the way. Would have gotten that one right too if I didn’t try to second-guess what they’re trying to say.
90%. I never studied physics, even in high school, so I don’t know from vectors.

87.5
Put me down as another doper annoyed with the cloud question.
70% ouch…
Eh, what does Newton know anyway…
90%. I call bullshit on the cloud too.
Campion I hate to break this to you, but with a T/F test you get 50% just by chance 
77.5%, and I want to be an EE. Atleast I can say that I have never had a single physics class besides chemistry, so I did poorly simply because I suck at teaching myself.
77.5% (which I thought was not bad but compared to you nerds I’m not so special)
Oh he was some sort of Astrology and Alchemy nut, who would beleive such a person ? 
72.5%, and I’m happy with that. I have a fine arts degree, and I never studied physics in high school or college. My familiarity with scientific subjects is entirely due to reading of lay-oriented material as an adult. Given that, I think I did pretty well.
Not quite true. You don’t get 50% on a T/F test “just by chance”; you mean, instead, that by guessing (without reading the questions or attempting to answer them), you’re likely to get half right. For kicks, I just retook the test, guessing “false” for all questions. Guess what? 67.5%.
And yet, for some reason, I’m still kinda proud of my 50%. But I think I may spend a wee bit of time reading this weekend. Just so I can bulk my score up to the 67.5% “guesswork” level.
It’s standard high school physics to demonstrate that steel at room temperature feels colder than, say, cotton fabric at the same temperature, and that the sensation has as much to do with conductivity as with temperature. I agree that some of the questions were worded in a rather colvoluted way, but this one wasn’t technically incorrect, and if you got it incorrect by thinking too hard about the wrong aspect of it, then tough!
80% - some of them I agree I got wrong because I wasn’t thinking clearly, others are an argument over semantics, and some of them try to confuse between the theoretically correct answer, and the practically correct answer.
- For example. They set up an engine with no frictional losses, and no unwanted heat transfer, then claim this magical device is subject to Carnot’s law anyway. I knew it was a bullshit machine, the only question was where would the bullshit stop.
Agreed, some of the questions, in my opinion, were ambigious. Clowds have dust particles, for instance.
But, no sour grapes for me, I got 53 percent. :::Looks away in shame::: :smack:
That’s a pathetic excuse …all they were needing was a realisation that the ignition of a fuel results in various forms of energy, not all of which are useful. How would you ignite petrol vapour without any sound being emitted?
Actually, the ‘cloud’s mass’ one I will concede as ambiguous, because defining a cloud is kinda tricky
I’d do it in a vacuum.
Oh wait, you need oxygen.
OK, I’d do it in the middle of a forest, without anyone around to hear it.
I nailed 90%. Economics degree. Go figure.
I missed 6, 8, 15, and 21.
Water vapor’s invisible. When they say the humidity is 88% and you walk outside and you can’t see any fog, that is because it’s water vapor. Clouds are made of liquid water. The question and its answer are correct.
90%
Not so good considering I have a physics degree!
The dictionary notwithstanding, in science lingo a vapor is a gas. This is a physics test, not a test on the vernacular.
92.5% for me.
