Whether or not the motion is towards the left or right again depends on the magnitude of the acceleration. The acceleration could be strong enough to compact the motion such that its bend to the right like your last drawing. But it could also be weak enough so that it only compacts the motion a...

Theres a simple trick to all of this. And that is to keep Lenz's law in your head. The law says "changes can induce currents and these currents will set up magnetics field to oppose the change" So for your scenario: Change =North Pole approaching Left side of Solenoid Then the induce...

Suppose we are to draw it from the point of view of the observer inside the train, then he would observer an horizontally compacted version of a projectile motion. Now how compacted this motion is depends on the acceleration of the train. Since we are not given this information, doing this...

Ok few more things i can point out to convince you that I am right. Firstly the drawing given is clearly from a perspective of an observer outside, this is irrespective of what you wrote. Only motion studied in HSC physics in any depth is projectile motion. Try and draw the motion of the...

I think the question is asked as if you are an observer outside of the train. Since that reference frame is inertial what I said holds.

a. because the train is accelerating b. it will be just be a regular projectile, with initial velocity given by the velocity of the train at the time the string is cut. This is because the only force acting on the mass is gravity. Newton's Laws do not work in non inertial frames and things can...

Re uploading my notes.

The answer is simple. You just have to think about the real purpose of proposing a medium for light in the first place. (the purpose is not just so that light has something to "sit" in and then attach a fancy name to the medium, that idea is trivial and provides no real purpose)

phys shirt had schroedinger's wave equation but it wasnt witty enough

but the spherical cow integral shirt was so cool!

Does our uni have a mathsoc and if so does it sell t-shirts?

I love how Wildberger goes to lectures with nothing but a peice of chalk in his pockets.. And you guys dont get Bruce Henry for calculus?

Decided to post more of my biology notes. Everyone seems to be in need for communications notes, so i released it before search for better health. Anyways, post any mistakes and corrections (i will give you credit for finding/correcting) Constructive criticisms are welcome.

Hi yr 11s, Question: when do you finalize your subjects for yr 12? (or has yr 12 already started for you guys >.>)

You can obviously separate humor into 2 categories, mature and immature, guess which category your friend belongs in? You guys are in yr 12 and beyond, show some basic manners and maturity.
