V(t) = V(0)*[1-e^(t/RC)], we have 8 =

**12***[1 - e^(-1/RC)] or 0.6667 = 1 - e^(-1/RC) or e^(-1/RC) = 0.3334 or -1/RC = ln{0.3334) = -1.0996 or RC = 0.910 or C = 0.910/12000 = 27.78 microfarad2 Answers · Science & Mathematics · 08/04/2011

styraphome balls ranging in different size, medal wiring(medal clothes hanger), paint and build from there. if you want to get real sophisticated, use a flashlight for the sun, its good with explaing the phases of the moon :)

ans e) 3200 N/m reason : it is bcoz,potential energy of a spring=1/2.

**k**.x^2 for first spring,**k**=800 N/m , x=**12**cm for second spring,**k**=? , x=6 cm equating & solving the equation,we get 3200 N/m ans.3 Answers · Science & Mathematics · 12/07/2008
