Electrical systems are governed by ohm's law, which states that vequalsir, where vequalsvoltage, iequalscurrent, and requalsresistance. if the current in an electrical system is decreasing at a rate of 6 a/s while the voltage remains constant at 12 v, at what rate is the resistance increasing when the current is 20 a?

0.09Ω/s

Step-by-step explanation:

V=IR

12 = 20 R

R = 12/20

  =   0.6 ohm

dI/dt (R) + dR/dt (I) =0

-6 x 0.6 + (dR/dt) x 40 =0

40(dR/dt)  =3.6

dR/dt =  3.6/40

         = 0.09Ω/s

the ratio of grapes to blueberries she should use is 12: 3

step-by-step explanation:

if mandie is making 15 cups of fruit salad, the ratio of grapes to blueberries she should use is 12: 3.

gmt is 4 hrs ahead of edt so just add four hours to 1: 14: 20 (minutes and seconds stay the same)

gmt is 5: 14: 20

hope this !
