so I posted a very general quiz on another forum I go to; here were the questions: Quote: 1. If I take a 500 mL Erlenmeyer flask, add 200 mL of distilled water, then 10 mL of 1 M NH3, then 10 mL of 1 M HF, then heat the mixture to 100°C using a Bunsen burner, what will be the final pH of the solution? 2. If 10000 chinamen weighing 120 lbs each simultaneously jumped up and landed at the same time, how far would the Earth move in the opposite direction in meters? 3. Explain why some people's shower curtains "attack" them when they turn on the water. 4. Describe Nietzsche's theory of the Superman. 5. For what is Pope Pius XII often criticized? 6. Robert Browning's Porphyria's Lover is what genre of poem? 7. Who won the 2005 Nobel Prize in Mathematics? Note number 2: I wanted an answer in meters, but some dude apparently thinks that if you go into fractions or decimals of a meter, then it isn't a meter at all: Quote: You asked in meters. Since it's less than one meter, it's the only correct answer. Quote: That's like asking for an answer in feet and the correct one being inches. Quote: since you wanted either a fraction or a multiple of the "meter" you weren't asking for an answer in meters at all. Does this bother anyone else? neutral

Silly Baron, everyone knows that fractions aren't numbers. They're just lies by the government working in collusion with the math teachers.

Those questions seem so unrelated. What was the forum?

Yeah, they are unrelated. It was just a quiz to see how much people knew.

I know the shower one... It has to do with the speed of the water decreasing the pressure inside the shower. By decreasing the pressure, the curtain is pulled inward. It is all a basic application of the bernoulli's (spelling?) principle.

I think I could get all of them but number 6 (I really have no effin clue). Number 1...I mean, it's been 5 years since my last chemistry class, so it would take me a while anyway. Number 7 is funny, and number 5 is just kinda random knowledge. What made you choose this set of questions?

I wanted a set of questions that didn't focus on one particular thing. If anyone got them right, they usually got the last ones right, not the ones dealing with science.

It would bother me.
I mean 800cm is 0.8m.
Though it would be weird to say it was 4/5 m
And when it comes to comparing different measurements you have to putthem all into a common measurement, even if that means some are only decimals of thatmeasurement.

I say there's a temporary displacement in the Earth's position that depends on the distribution of people on the surface [uniform distribution will impart no nett force]. It will be absolutely tiny, but it should be calculable. Of course, I could be missing something, but the act of jumping is putting energy into moving yourself [the source of the energy comes from the food you eat] so there would be some corresponding movement in the Earth, but no overall displacement.
Like I say, there could be something basic I've missed; I've been known to do it before. XD

Baron von Turkeypants so I posted a very general quiz on another forum I go to; here were the questions: 1. If I take a 500 mL Erlenmeyer flask, add 200 mL of distilled water, then 10 mL of 1 M NH3, then 10 mL of 1 M HF, then heat the mixture to 100°C using a Bunsen burner, what will be the final pH of the solution? I don't know chemistry...and didn't really read the question (I'm sure it's a trick and the answer is something like 0, though). Quote: 2. If 10000 chinamen weighing 120 lbs each simultaneously jumped up and landed at the same time, how far would the Earth move in the opposite direction in meters? It wouldn't. When they jumped up, the earth would have picked up a momentum of equal magnitude but opposite orientation as the Chinamen. It would have moved, but the mutual gravitation between the Chinamen and the earth would bring it back into position. When they land, the earth wouldn't have moved at all from before the time they jumped and the impact would have voided both the earth's and the Chinamen's momenta. So the answer is 0. (This amounts to saying a system's center of mass can't accelerate due to only internal forces.) Quote: 3. Explain why some people's shower curtains "attack" them when they turn on the water. The moving hot water heats the air and causes it to move, both of which reduce the pressure inside the shower relative to the pressure outside, causing the curtain to accelerate towards its unsuspecting victims. Quote: 4. Describe Nietzsche's theory of the Superman. My ex loved Nietzsche and wouldn't stop talking about his superman crap about 4 years ago. I didn't care enough to remember. Knowing her, it probably had to do with abondoning your inhibitions and empathy for others and just looking out for your own self interests... Quote: 5. For what is Pope Pius XII often criticized? There was a Pope Pius? Quote: 6. Robert Browning's Porphyria's Lover is what genre of poem? *shrug* Quote: 7. Who won the 2005 Nobel Prize in Mathematics? Finally one I know. There isn't a Nobel Prize in Math...its equivalent would be the Fields Medal. Well...I clearly don't know much outside of physics... >.<
