mmm..okaaaayy .... i'm trying to use my stupid brain to think.....now listen moi,,,,, area = pie * r squared, so resistance increases by *2 squared NOT 2 so multiply the resistance by 4

GUYS HOW DO WE SOLVE QUESTION 11 PART B) II) OC/N 2011 VARIANT 3
http://www.xtremepapers.com/papers/CIE/Cambridge IGCSE/Physics (0625)/0625_w11_qp_33.pdf
Which paper dude?dunno idf its diff but plz xplain 9 (c)(i) , also they've given valur in Kelvin n not C , what 2 do?
no its question b ii)Beta particles are negative, -1 in the proton number.
Meaning you ADD one proton. In the question carbon has 6 protons, so just add one.
Proton number will be 7, and of course nucleon number will increase by one as well since nucleon number = proton+neutron.
Oh okay..... I believe now i got it !! Thank You soooo Much !! Sorry for frustrating you ^-^in the QN its mentioned dat diameter is halved!!! so radius inverse of 1/2 is 2? u then square it 2 NOE THE RESISTANCE.
hope u got it.
no its question b ii)
not i)
OH THANKS :OOh thats easier, you know that it's half life is 5730 right? And it says recent human skeletons, meaning ones that JUST DIED have an activity of 64, but the one they dug up had an activity of 8.
So we half 64 which gives us 32, so far the skeleton is 5730 years old.
Half 32 now, and we get 16. Age is now 5730+5730
Half 16, and we finally arrive at 8! The age of the skeleton is 5730+5730+5730=17190 years old x)
OH THANKS :O
U do done wid everything geniusAnytime, anyways I'm off guys. GOOD LUCK WITH STUDYING!
ANd good luck with tomorrow's exam!
Again can u Temne the paper ?dunno idf its diff but plz xplain 9 (c)(i) , also they've given valur in Kelvin n not C , what 2 do?
exactly why I dont search them for u coz I dont know either ....sry....
WHICH Paper????????!!!!!!!!!!!!dunno idf its diff but plz xplain 9 (c)(i) , also they've given valur in Kelvin n not C , what 2 do?
Moment= forceX perpendicular distance of the line of action of force to the pivotHey
anyone knows the formula of the moment of force??
