yes holes r just an empty spaces within the lattice due 2 group 3 dopant.
if i got a hole wid an electron in it 2 the left and another hole on the right.. ie only a hole on the right, and the electron moves to the right. it is sed the hole moved 2 the left

4D
5C
6B *i could b wrong for this* in Q it says "wire of very low resistance"
7A remember its a GENERATOR
8C
9B

15D use right hand palm rule... electrons up holes down
its gonna b close to 83. last yr my frend got 83 n got scaled to 93. but this yr was easier than last yr. n easier than trials =) easier than last yr so scaling wont b as good
therefore band 6 = 83
beta decay u do get anti neutrino. it was orignally called the neutrino but research showed it hav anti matter propeties. so it was renamed the anti-neutrino
but still there will b induction only that is isnt continuous as in Q
think abt moving a rod in a B field at constant velocity. the rod will still slow down becuase of tempt induction but then cruise along at a slow speed then wen it entered the b field
