Re: MX2 2016 Integration Marathon I've just started integration 4u, and am looking through this read from the beginning. How do you guys do Integration by Parts so quickly? I'm sick and tired of writing u and u' and v' and v

Explain how the results of the Michelson and Morley's experiment can be used to support Einstein's assertion that the speed of light is constant. [3]

Re: MX2 2016 Integration Marathon Can someone explain to me from step 2 and onwards? I'm a little confused? I know that cis(2x) - cis(-2x) is -2isin(2x) but like???

Thanks guys, I'll keep that in mind!

Hi, can someone please help me with my homework (1) (2)

Re: HSC Chemistry Marathon 2016 Tbh, I just study a lot. If you're having problems answering questions here, then you should use UR notes to help you answer

Re: HSC Chemistry Marathon 2016 Alkene series being more reactive than the alkane series is due to the high electron density associated with the double bond in alkenes. Isn't this reason a bit more simpler?

Re: HSC 2016 3U Marathon I loved this question

I don't think geosynchronous orbit is in the syllabus but I saw in one of the Independent Trials they asked about it, so it's good to know

NEXT QUESTION: 1. An ice skater coats around a uniform circular track at constant speed. Compare and contrast the motion of the skater with the motion of a satellite orbiting the Earth (3M) 2. Europa and Lo are the moons that orbit Jupiter, and Europa orbits (orbital radius) at a distance of...

Re: HSC 2016 4U Marathon oops

Yeah lmao

I think he meant the rotational motion that is greatest along the equator

That's fine, you just gotta talk about the direction in which the rocket is launched (to the east) which gives the rocket a velocity boost due to earths rotational motion and this velocity is maximised from the location the rocket is launched from (equator), lower 'g' due to larger 'r' is a...

I'll mark you later, I gotta go out soon. However, in the meantime, NEXT QUESTION: Discuss some strategies used to minimize fuel consumption of rockets (3 marks).

NEXT QUESTION: The centripetal force required to keep a satellite in orbit around a planet is provided by the gravitational attraction between the planet and the satellite. Compare a low earth orbit satellite to a geostationary satellite, and in your own answer explain why geostationary...

Galileo was the first to use mathematics to analyse projectile motion. He considered that, rather than using the motion of the object as a whole, it could be split into the constituent vertical and horizontal components (note that they're independent of each other), and when added together as...

Re: HSC Chemistry Marathon 2016 Nevermind, I'm convinced it's incorrect now. Yeah it's A dw. NEXT QUESTION: To determine the concentration of Fe2+ ions in a sample of tank water, a student conducted a titration of a sample against a standard solution of potassium permanganate. The reaction...

Re: HSC 2016 2U Marathon What's the Shells Methods? Can you explain, just wondering

Re: HSC Chemistry Marathon 2016 Yeah I know you always flip the sign on the one that gets oxidised but I don't understand why it's not A and not D. Confusing me tbh
