i think its LENZ's cause thats where the negative comes from.

and for the magnetic thing isnt N at the left :(


i think it is faraday becuase the question for the graph says sketch the AMOUNT of the emf in the thing  and it didnt say sketch the direction of the emf

It is indeed Len'z Law.

Also, magnetic north pole was on the left.
I don't know whether iTute's answer is wrong or whether their wording is dodgy ><.

Question 4 Sound: Richard was standing 20 m from the same sound source. Give the best sound intensity level:

I2 = I1(r1/r2)^2 = 10^-5 x (5/20)^2  = 6.25x10^-7
So L=10log(6.25x10^-7) + 120 = 58 dB
Answer is C
