I think I messed up the period for the satellite
otherwise quite easy!
[quote: How did eveyone go? I got the damn Av gain wrong, did 3 on 120x10^-3 instead of 6 ]
120,000?? why the negative power?
"Think i got the spring energy questions wrong also."
0.2J in the spring?
And the two multi choice graphs D and A? - inverse parabola ( like a mountain) for kinetic energy, and straight (positive gradient) line for the GPE?
I got .2J, It is correct [as far as I know]
Definatly wasn't the parabola.
Kinetic energy at the bottom was highest, and at the top was 0 [as we know, velocity at a turning point of its motion is 0]
So for Q13, Answer was B.
For Q14, Gravitational potential started at 0 [remember, potential energy is relative to a point]. And as the ball went up, the potential got higher. Answer was A.
[I got a copy of the question book infront of me]
For the satellite one i had F= 2900 something and T= 7180 seconds. Resistance for the cooler in the classroom should be raised and i think my voltages were 2v, 3v for the transistor but i cant remember what the last one was asking for. The graph i got inverted of vin but capped at 3 and -3v. Justing trying to remember answers atm.
Umm 0.07ms^2 for acc of boat, 4ms max speed.
Relativity. answer was b for first one, had 150m for electron, 3.6x10^4j i tihnk and the rest will come.
Sounds right,
Question 4 of Electronics was asking for power dissipated in Rc [I think you were refering to that]
Graph capped at -3 and 3, inverted.
