the reaction force is the gravity of the satellite acting on the planet, however because its mass is so small, the effect is negligible tbh tho i dont think im going to be able to sleep until i get my marks

you might be better getting some sleep now and then getting up earlier in the morning and doing some study

nah the satellite is kept in place by its velocity not a counter force, centrifugal force is a pseudo force resulting from trying to explain the inertia of objects in a non inertial frame

yeah fam

was at constant velocity at the start, meaning it had no acceleration and therefore no continuous force applied to it, so if it loses its kinetic energy and there is no force pushing it, it wont gain any kinetic energy

u dun fucked it up at the end

yeah thats exactly what i was thinking, just cbf bothering to go into that much detail for 5 marks for a graph & justification

it doesnt increase at all tbh, because it slows down approaching the field due to lenz law repulsing the cutting of magnetic flux, however once its in the field, the same thing will want to stop it from leaving

mine was like a sideways cubic function tbh, idk tbh

mfw put the radius at 200000 not 6580000 fml, well the good thing about it being a 3 mark question is that i will most likely still get 2 marks cus i wrote out all my calculations and values and shit

well the escape velocity formula isnt on the datasheet, so if someone one didnt remember it then they would have to derive it which would probably be worth 3 marks for the 6 mark, i wrote a lot of shit about the launch e.g. thrust, reduced mass from the fuel, escape velocity. i didnt have much...

RIP those who didnt learn hertz's experiment

that was a different question wasnt it, you wouldnt have to derive it but for the 6 mark space one, it would have been good to explain that orbital & escape velocity are derived from the universal gravitation law

question was talking about F=Gm1m2/r, which give equations such as escape velocity & orbital velocity

nope the conductor one was clockwise with change in flux because it will induce a current to oppose the motion of the wire, and the flux density wasnt actually change because it was the same field the parallel conductor one was F/2 to the right, because the middle conductor repelled it F to the...

there was like projectile motion, relativity, that 6 mark one at the end, wouldve been at least 15-20 marks

what lol

There was heaps of space stuff, what you talking about

lmao savage fam

it had 5 digits, thats all i remember lmao, possibly starting with a 2
