low voltage means higer current... so thicker cables are needed? i agree, stupid question say that that formula iss for an 'ideal' transformer... some energy is lost due to heat

hi

this is how you do it For something monoprotic: HCl\to H^+ +Cl^{-} $mole ratio$ 1: 1: 1 For something Diprotic as H_2 SO_4 $mole ratio$ H_2 SO_4 \to 2H^+ +SO_4 ^{-2} 1: 2: 1 Hence, with something triprotic, you divide the moles of the triprotic acid by 3 to get the moles of the H ions. so that...

ur welcome... and thanks for the rep :p

ok the first part... you sub in x= sqrt(-q/y) P(x)=x^3 +3px+q $subbing in $x (\frac{-q}{y})^\frac{3}{2} +3p(\frac{-q}{y})^\frac{1}{2}+q=0 (\frac{-q}{y})^\frac{3}{2} +3p(\frac{-q}{y})^\frac{1}{2}=-q $Upon squaring both sides$ (\frac{-q}{y})^3 +6p(\frac{-q}{y})^2 +9p^2 (\frac{-q}{y})=q^2...

for the second part, its aksing to find the relation between the co-efficients... product of roots is alpha X beta X gamma = gamma^2 = -q hence gamma = sqrt(-q)... then sub it in

practise on this one: y= \frac{x^2+2}{x+1}

10!!!! why are threads like these still going... do 11 at most

are you pressed for time during STAT?

95.05

you can times both side by -1 first, to get rid of the negative sign infront of the x^2 term.. so you get X^2 -3x-4=0 by inspection... or using the quadratic formula on ur calculator, the factors are 4 and -1 hence (x-4)(x+1)=0 or use the cross method as mentioned above X -4 X...

or you all suck

use the auxiliary angle method

I am sorry to inform you sir, but moving at such speeds is not possible. According to Einstein's theory of special relativity, published in 1905, nothing can exceed the speed of light.The same theory says that objects gain mass as they speed up, and that speeding up requires energy. The more...

QUOTE:tall, dark, smells good, buff sweet, daring, laid back, bit edgy oh fuck im just describing my ex... oh well END QUOTE your ex eh? ^^ How you doing ?:D

well u only need to prove it for 0<x<1 because, any number bigger than 1 will make the eqn positive as x^3 dominates...i may be wrong... im thinking of tangents to sinx curve to prove it but i am going no where

no girls out of the 98 who do physics at my school :D

your mum in the future... addicted to pot

95?

yeah now that i think about it, i guess ur right... seeing how he is getting 1.4% for physics... im sure an average kid will get something like 50/71... just being frank OP
