yeah,,and i shall quote the question. hence, greater distance is measured~?

yeah .. so lets use a diagram: normal train; with velocity to the right at a low speed |<---------------------------------->| train undergoing velocity of 0.9c going to the right |<-------->| [hypothetically] therefore, wouldn't it cover a larger distance? o_o

note, tht's onli the train undergoing contraction. hence, it must travel a longer distance in comparison to the distance that inside the frame of reference travelling. hypothetically; normal train travels 100m [at, lets say, 60ms-1] inside a train travelling at 0.9c, it travels 100m...

wat bout in reply to what i had? o_O

okay, here's the exact wording of the question: emphasized the MORE part and hence, i believe .75MJ is correct

it's 2 marks :P yeah i put .192 but it's wrong. sure, it may have no contraction in the electron's frame of refernece [wtf?] allowing it to measure .24m however, in the external frame of reference of by scientists, the electron is 'squished' [in easier terms :P] so tht it has to cover a...

yeh, ,i put b. it's A [for question 10] there is gonna be constnat current /voltage flowint through coil x when the switch is closed. however, coil Y requires a change in flux to create a current [achieved by opening and closing the flux] and hence, voltage is induced in coil y

lol, these guys are just trying to psych u guys out. 2. B think of the hammer throwing in olympics [ string attached to mass, guy spins round and round and lets go of string ]. when the guy lets loose of the string, it flies off in the tangential plane. also another example is the...

i disregarded the e's :P all u gotta worry bout was the +2/3 n -1/3 lol

yeah wOot! =D =]

came 1st in school with 94% in independent [i think] trial. well schools ranked in 200-300ish ..

lol u should ignore that kid, taurus and bobby rocks are troll accounts i think~

if my understanding of the system is correct, both you and the first place guy would get 93. but don't take my word for it

state the horizontal component of the projectile when the object lands. asking u for the horizontal component : doesn't change.

hmm. what's with all the trolls. -_-"

and approx how many ppl do business this year..? lol i might be in the top 4-6% .. haha *hopefully*

yay. tht means there's a chance i'll get either 13-14/15!! =D woot ! ^_^

well they have to accelerate to get into the earth's atmosphere don't they? when they geti nto the earth's atmosphere, THAT'S when they'll slow down due to the friction. i stand my ground. =]

lol. ur gonna get a b6 for sure!

range = 8 seconds. and then u calculated it by multiplying 45 x 8 = 360m hence, range = 360m?
