    I got stuck on these multiple choice questions and looking back over them I still don't know how to do them. So would appreciate some help.

    Question 11 I don't understand what you need to do. 0 gravitational field strength?

    For Question 22 i'm confused also, (my hardest topic, electromagnetic induction)

    For 24 I think its something to do with the coils? Step up transformer so linkage is higher, but still don't understand the 1's

    Any help greatly appreciated & repName:  Untitled1.png

    For 22 think about the total area that the plane flies through in the 10 seconds. Then just multiply it by B.

    living up to your screen name?
    Refresh your memory on the relationship between the unit tesla and the unit weber.

    For 11 you need to find the period of revolution at which centrepetal acceleration minus acceleration due to gravity equals zero.

    How am I living up to my screen name? The questions don't have any method shown, anyway I worked out 24 & 11 now.

    worked out 22 now, didn't realise you had to use d=vt, thanks anyway
