**Reiny**, Sunday, January 20, 2013 at 8:44amC varies inversely as J ---> C = k(1/J) , where k is a constant

when C=7, J=.7

7 = k(1/.7)

k = 4.9

so C = 4.9/J

when J=12

C = 4.9/12 = .408333..

or:

C1/C2 = J2/J1

7/C2 = 12/.7

12C2 = 7(.7)

C2 = 7(.7)/12 = .408333..

notice the actual calculations are of course the same.
