Physics Electromagnetic Induction question A level

Svesh

I don't really understand what and how to use the numbers in this question.
PH5 -2015 wjec Q2

Need to calculate the resistance = resistivity x length / cross section area (of wire, not loop!)
Need to calculate induced emf from change in flux linkage / time.
There's extra info you've nor shown (I assume) such as B at times 0 and 0.12s.

There is not enough info to solve the problem. Info like how fast the loop is rotating and what is the magnetic flux density.

Post a clearer picture or post a link to the paper.
