thanks guys!

^ well if I shine a light beam on a mirror surface, it will be completely reflected off, so can we call mirror a blackbody ???

can someone explain me all aboutblackbody radiation and quantum physics etc 1- what is a blackbody??? 2- what does it mean that the energy radiated from a blackbody is quantised? (dont just tell me that it has discrete values and is not continuous- i already know that! but i dont get it...)...

does anyone have an idea what 56/70 will align to???

the average cutoff for 3 unit is around 68%...it's illogical if it's 70% for 4 unit

can someone please tell me what will 55/100 align to???

not sure but about 65-67/105....just an estimate!

anymore estimates??

school rank- 380s eng. adv- 7/12 3 unit maths- 3/20 4 unit maths- 1/3 physics- 1/47 chemistry- 1/35 what atar am i looking at the moment?? also if i do good in hsc (say band 5 in english and band 6 in the rest), what would be my expected atar?? thanks!

Equal volumes of four 0.1 M acids were titrated with the same sodium hydroxide solution. Which one requires the greatest volume of base to change the colour of the indicator? (A) Citric acid (B) Acetic acid (C) Sulfuric acid (D) Hydrochloric acid i chose sulfuric since its the...

your trademark line..!

so 99+ is achievable?? and what about actuarial studies, my career advisor says both are good..

school rank (380s) Advanced English- 7/12 Phys- 1/47 Chem- 1/45 3unit- 2/35 4unit- 1/3 Also, if i want to do actuarial studies, which is better unsw or macquarie??

i realised my mistake...i got that! thanks

for OP i got 40ln2/5 + 600 ??

again why did u multiply 30+ln2/5 by m, where did it come from??

lol when i posted this question, i was 100% sure u will be the first guy to answer it..thanks! edit- i though air resistance was a force itself, not acceleration

a car is travelling along a horizontal road with a velocity of 30 m/s. the engine is stopped at a marked point O along the road and then the car coasts to a stop at a point P. Frictional resistance is 1/10 of the weight of the car and air resistance is v/20 per unit mass, where v is the speed of...
