Question

HELP!
R=KL/d2 (d squared)

Answer 1

what do you need to do..?

Answer 2

oh solve for d

Answer 3

ok... multply both sides by d^2 which will get d out of the denominator

Answer 4

and i would get R(d^2)=KL?

Answer 5

you now divide both sides by R

Answer 6

last step will be taking the square root of everything on the right hand side...

Answer 7

d= the square root of KL/R ?

Answer 8

yes... now I'm not sure how musch you have done on taking square roots... but there is actually 2 answers... normally written

\[d = \pm \sqrt{\frac{KL}{r}}\]

Answer 9

oops should be R

Answer 10

ohhh I see . thanks . i have another one .

Answer 11

\[\frac{ V _{p} }{ V _{s} }=\frac{ N _{p} }{ N _{s} } solving for N _{s}\]

Answer 12

cross multiply then divide both sides by Vp

Answer 13
