, hi again; helpppp please?
First one B?
Wait, so for a generator what do we use and for a motor which do we use?
nupes.. first one A, :/
12) A .. there a vacuum created so pressure is 024) A .. all rays are parallel .. so they will emerge through the lens parallel
I had a similar question and i still dunno why its zero :S Second one is D
D? "CONVERGING" lens...says it all..
How is it D .. it should be C .. cause the middle ray which passes through the optical center should pass undeviated so its C >_<
