hold on a second,,, from the table A3, physics is capped???!?!?!?! (this defies the laws of physics!!) Max Mark HSC:49 scaled :50 so you get a scaled mark of 50 but you can only get 49?? and do you have to times all the values by 2??

what is needed to full answer this dot point; •Discuss the importance of Newton’s Law of Universal Gravitation in understanding and calculating the motion of satellites. is it just that we can workout the orbital velocity of a satellite? and while we are at it, how about this one...

the angle isn't the velocity

is this M. Toumas??? its andrew lol

where in the motion of a pendulum, it the acceleration of the bob( mass) the greatest? and why? cheers

i just wanted to know where everyone is up to in the 4 U maths course. so far i have only had 5 lessons and we are doing de-movier's therom next lesson. already done vectors and operations on complex numbers. i heard that some schools have finished complex numbers and are currently doing volumes

for me, chem is probably my fave. subject. and i just thought that is should make a thread to show my love for chemistry..... if you like chemistry, post up why.

finish complex numbers. finish space (physics), finish acidic environment (chem), read Frankenstein and do UMAT!!!!:hammer: and learn ahead in physics and chemistry

what school do u go to?

AHAHA, yea i attempted the question already. i did it again and i realised that i got the volumes mixed up. thanks .wysiwyg { BACKGROUND: #ffffff; FONT: 9pt verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif; COLOR: #000000 } P { MARGIN: 0px } .inlineimg { VERTICAL-ALIGN...

Hey world. i wanted to know if anyone could tell me where the answers are to the HSC papers??/ i did question 23 from the paper and i want to know if i am correct or not cheers, ps, i got 83.333 grams. i just found the answer in a success one book and the answer is 82.0 grams...

How can you improve the accuracy, validity and reliability of a titration??

i hear that you cannot use "I"

when plotting atomic number against reactivity you get all these peaks at sodium,and all the group one metal

if you live so far from school, go to a closer school. they will not give you bonus points for that. it also takes me like 50mins -1hr 20mins to get to school. and it really sucks when i have to go before school to attend period 0. suck it up, i assume that you have been going to the same school...

i have T^2 as my y-axis and L as my y axis. i then do rise over run to get the gradient. Right now you're using T^2 = m(L) But m = T^2/L these are the same thing but you just cross multiplied. hmm ill try graphing it again

Im pretty sure that would also apply at my school. this is how i did the experiment. i change the length of the string, i put the mass in motion and time the period of 10 complete swings from the top of the motion. i then get the average period of ONE swing .i repeated it like 4 times (and...

when you draw you line of best fit, can you use the gradient to find the value of 'g' becuase when the formula is re-arranged, you get T^2 =((4*pi)l)/g in terms of x and y, T^2 =y and l=x therefore, from y=mx, the gradiaent will equal 4*pi on g. when i do this i get g to be 11.25ms^-2??? or...

if you can see that the dots roughly form a straight line, then use a ruler. if it is obviously going to be a curve, go over the path that the curve is going to take by hovering you hand above it. once your happy with that motion that you are doing with your hand, then put pencil to paper...
