Am I the only one who put 2.62 radians for the conversion from 150 degrees? 1 radian is 57.3 ish so I divided 150 by 57.3 and got 2.618 something.. Probs wrong

12000ns (b) for question 2 about momentum?
20,000n

8000 kg x 2.5 = (12,000+8000) x 1

The moon is pea size compared to the Sun, surely the sun would give a larger force?
I got E>S>M..

I thought moon would be more than sun since the moons distance was smaller than sun's

Depends how far away the sun is though doesn't it
They gave the values in the question so I presume you can use them to work out the value of g . I did this and the sun had a larger value than the moon

would the sparks be brighter for the capacitor question?

I put that although energy stored would be greater, it wouldn't be brighter as the energy would just last longer instead

I didn't get that question, it asks for gravitational strength on the satelitle, but it only gave distances from the earth to the sun/moon

it didn't give the distance from the earth to the satellite

I guessed B in the end, thats wrong isn't it?

20,000n

8000 kg x 2.5 = (12,000+8000) x 1
The question asked for the change in momentum of the 8000 kg truck, so the momentum before was 20,000 and the final was 8,000 giving a change of 12,000

did anybody get 150 degrees and pi/3 for 5a?
it was rotating anticlockwise not clockwise so the answer was 60

Probably said the sattelite was near the earths surface

oh yeah, for the induced emf graph, everyone started off at zero, right?

but did you draw it sloping up (to the positive part of the y-axis) in the first quarter of a cycle?
