You say that both are used for motion... But the back emf in a also applies motion. Still you got a point. Here's hoping they mark both c and d right when they realise what a gay question it is
Fall of the Roman Republic
Augustus and the Julio-Claudians
Periclean Athens
Pericles
I aced the first three parts but didn't have enough time to finish the last question. Argh! I'd say I get somewhere in the 80s
Faraday's Law is that a changing flux induces an emf... Which is true for d, but isn't it also true for eddy current breaking? The emf causes the eddy current doesn't it?
The one about the application of conservation of energy in the same way as electromagnetic braking, in which every answer could be right. Everyone in my school is arguing over whether its c or d. I got d cause they both have eddy currents. What did everyone else do?
I finished, but some of the stuff I wrote was a bit bs. Is there meant to be two north pole magnets in that motor question. I didn't think there was...
I doesn't surprise me. Sport and English? What an evil idea. I'd rather watch the mould grow on cheese than do this - at least there's actually some interesting stuff in other English modules
