Civil Engineering (:

If anyone needs, i can tutor chemistry (90/100), Maths Ext-1 (95/100) and Maths Ext-2 (91/100). Just msg me through the inbox and we can work out a time and place :)

btw what you guys think a 85 raw scales to?

i like how people just forget that there is space dust which causes drag to the object droped from the equatorial tower... it will be in geostationary orbit and then make its way slowly to earth. (thought experiment)

i recon ill get MC:17 LR:48 OP:22

the acid in the dry cell eats the zinc and is released into the environment. Usually rain dilutes the acid and it is not an issue, however in areas of little to no rainfall the acid will damage the soil and kill many organisms that decompose waste... etc

best case 96. worst case 85 :)

well i guess the head teacher of physics at my school is wrong ? or maybe multiple answers are accepted along with justification? or maybe the object is dropped instead of thrown? think about a tower not that high (centerpoint tower, assuming its on equator) and assume atmospheric friction has...

dude it was dropped, regardless of its position it will fall to the earth. It is at a height of a geostationary orbit, however it is NOT orbiting the earth because it has not reached its orbital velocity. yes its orbital period is 24 hours when it is on the tower, but when it is dropped it will...

does NOT achieve orbital velocity when dropped :/ so how can it orbit. at poles it lands directly below, at the equator a half parabolic motion to hit the ground due to movement of the tower due to earth's rotation

depends what you got wrong, if u got calculation correctly written but u punch it wrong into your calculator u get full marks

is 85% raw enough for band 6, because i keep getting about that

i got 65% checked with Terry Lee :/ i hope its enough for e4 :(

well lets hope its lower then we all get higher :)

hmm i thought 9 was d :S

test had its difficulties, i recon ill get 65-75 with room for error included.I'd say cut off for e4 would be 70 in my oppinion

the last one was b. all integrals are odd except that one, which is even and the integral will be greater than 0 :)

lets hope we get e4 :)

last year 1st in the state for physics got 96% hsc mark and chemistry got 97%

seriously :S but dont you have to get heeps high to get e4?
