Jane’s quizzes

The questions get progressively harder; the harder the question, the more points it’s worth. See how many points you can score. (No Googling or cheating please. )

Mathematics & Science

1. If n is an odd integer, then n[sup]2[/sup]−1 is divisible by 4. True or false? (1 point)

2. What phase of matter is intermediate between solid and gas? (1 point)

3. What name is given to an integer greater than 1 that is not a prime number? (1 point)

4. Titan is the satellite of which planet? (1 point)

5. Whose law states that the volume of a fixed mass of gas at constant pressure is directly proportional to its absolute temperature? (1 point)

6. In August 2006, Pluto, Eris and Ceres were officially designated “dwarf planets” by the International Astronomical Union. What type of object had Ceres been known as previously? (2 points)

7. There are 6 “flavours” of quarks. Up, down, top and bottom are four of them. What are the other two? (2 points; 1 point each)

8. Which axiom of set theory is equivalent to Zorn’s lemma and the well-ordering principle? (3 points)

9. Name three chemical elements whose names begin with the letter “D”. (3 points; 1 point each)

10. Which mathematician in 1882 proved that π is a transcendental number (i.e. it is not the root of any polynomial with rational coefficients)? (5 points)

Re: Jane’s quizzes

Thanks, everyone! Here are your points.

careless25: 4 points
Identity: 3 points
ZHero: 4 points
Ricky: 5 points

It goes without saying that the more questions you try the more points you can score. However between the four of you you’ve managed to score 13 points out of 20. Good job.

Re: Jane’s quizzes

Well, if you used Google, then your answers won’t count, sorry.

I’ll be giving the answers before the next set of questions anyway, so be patient.

Re: Jane’s quizzes

If we assume that every (active) member visits the forum (at least) once in two days; then there's no need to wait longer than this!!
There are many enthusiasts (like ME) waiting for new puzzles and questions everyday!!
