The Math and Quiz Game =)
« on: December 05, 2007, 05:47:11 pm »
Same as Name the game but instead you have to give an answer to the math and/or quiz question.


Quote
Graphs

You are given 2 coordinates (1,1) and (5,5). What is the gradient?
Are the lines parallel?

Give reasons for your second answer answer.

1 point for each correct answer, total of 2 points

the gradiant is 1.


You have 2 lines cut by a line. The angles are for point a 30,30,150,150 for pont b 20, 20, 160, 160.
Are the lines parallel?



hopw I understood the rules right.

Very good altough it was a bit over detailed.

As a reason you should of told me yes, because they have the same gradient and because the values are bot positive and if divided by themselves they all give 1.

ok

You have a right angle triangular with sides 4 and 3 coulculate 3rd side.

...

Now back to the question you asked about gradiant.

sry I misread that I had to reason my anser. Can I have another question  :P ?

Its a 345 triangle so the 3rd side is 5.

You can also use Pythagoras' Theorem.

Which man in history was known as the "Iron Chancellor"?. The name has to be in full, not just the surname.

how hot will an iron bar with weight of 2.5 kilos get if it absorbes 780 kj (kilo joules). I have to coulculate for unser muself :p.

Edit: and I will not be peresent on forums till tomorow so you can ask next question.

You have to give me two more values: the change in temperature or the specific heat capacity of the iron bar.

sry just the heat change.


And heat compasity if I remember right marked with "C" is 480. I mean I am not sure what it is marked with but I remember the heat compasity. It is surely 480. Remmber it from science book. Just in case I will check by tomorow.

form wikipedia free encyclopedia

Heat capacity of iron "(25 °C) 25.10 J·mol−1·K−1 "


Dont get this but in my scince book it was 480 joules per kelvin.

30, 000 k?

Anyway its wrong as far as I know.


Sry I din't put much structure let me try again. C is heat compasity.

C= 480j/k
weight - 2.5 kilos
energy - 780 kj

Coulculate tempreture change in Kelvin.

this is not the formula. And if "Q" stand for energy it should be capital.

C= 480j/k
weight - 2.5 kilos
energy - 780 kj

(480*2.5)=1200 j for 1 degree kelvin of difference for the entire mass
780000/1200=650 degrees kelvin difference

They don't neccesarily have to be math questions. They can be from history,geography, language etc ..
