A resistance of 15 ohms and C=0.2 Farad is connected in series with a 30 V battery.
Determine the charge and current 0.7 seconds after the switched is closed.
O Charge (q) = -3.25 and Current(i) = 11
O Charge (q) = 3.75 and Current(i = 0.78
O Charge (q) = -1.25 and Current(i) = 2.58
O Charge (q) = 1.25 and Current(i) = 1.58

A 500 gal capacity tank initially contains a salt solution consisting of 200 gal of water and
3 lbs of salt/gal. A solution of 2 Ib/gal flows in at the rate of 3 gal/min and the resulting
mixture flows out at the rate of 2 gal/min. What is the concentration in the tank when it
starts to overflow?
O 2.352 Ib/gal
O 1.873 lb/gal
O 1032 lb
O 2.064 lb/gal
