the question said ANALYSE, so you'll need to specify WHAT forces acted on the space craft, WHY they acted the way they did and HOW these forces played a part during re-entry.
Simply stating that there exists atmospheric drag isn't analysing - that's just outlining.
Couldn't understand a word... I was at a complete utter loss... what the hell where they saying?! Ching chang mitsubishi judo teriyaki wang subaru??!!
fark!
Wrong, Wrong, Wrong, Wrong, Wrong, Wrong, Wrong.
-50*C is a negibile temperature and has absolutely minimal effect on the on the resistivity of the copper.
During re-entry, space craft SLOWS DOWN not SPEED UP. thus, its deceleration.
Hope you wrote that.
No spacecraft has EVER used rocket boosters to slow themselves down for landing...
Marking Scheme:
Mentioning Gravity .... 1 Mark
Mentioning centripetal acceleration is perpendular to earth's gravity... 1 Mark
Mentioning thrusting force to throw spacecraft off the orbit... 1 Mark
Mentioning that during re-entry, Spacecraft subject to DECELERATION forces ... 1 Mark
Saying that...

Next Question:
Mr. Jones's bathtub leaks water at a rate that is proportional to the volume of water in the tub. Continuously adding 5L/minute into the tub will just balance the loss through the leak when the tub contains 105 L of water.
One day, Mr. Jones could only allow the water to run...
I don't think the question is based number theory as Burnside Lemma implies. the BFC is used if we assume the circle to be a 3D object, (one where we can walk around)
But in this case, its not.
