6 out of 8 students got E4s in ext 2 at my school last year. Does that mean they got 90-100 as an HSC mark or 80-100??? I gues I'm asking if in an extension subject worth 2 units like ext 2 maths, does an E4 equate to 80+ or 90+
Basically there is a question asking for threee ways in which more current could be produced. Is current directly proportionate to emf?
So should i use the formula emf=nBLvsin(theta)?
So is an acceptable answer:
1. Increse # of loops
2. Increse Magnetic field strength
3. turn the coil...
