sorry dude i had C too but think about it.... u dont times it by sin 45 .... the angle is sin 90 because the field is perpendicular nayway.... yes u had to use pythagoras but it was sin 90
ummm for question 10.... it does the power supply is non alternating (ie DC)
it cant be d because they are inphase and transformers would have X at max when Y is at max
now if it is DC i think answer is A because initial circuit would have increase and then a plateau then drop off when it is...
Re: Japanese Continuers ... ridiculous..
listening.... meh
reading section was sweet
reading response .... i had gate crashers who did all the bad stuf
writing....meh
overall score ....meh
ok
E = -GMm/r
1x10^6 x (10 000 - 20 000) x 10^3/-6.67x10^-11 = Mm
Mm = 1.499 x 10^23 kg^2
now Mm is constant BUT it asks for the next change of work ie from 20 000 to 80 000 not 10 000 to 80 000
thus E = -GMm/r
E = -6.67 x 10^-11 x 1.499 x 10^23/ (20000 - 80000)x10^3
E = 1.66666.67
E...
