A constant current of 3 A for 4 hours is required to charge an automotive battery. If the terminal voltage is 10 + t/2 V, where t is in hours, (a) how much charge is transported as a result of the charging? (b) how much energy is expended? (c) how much does the charging cost? Assume electricity costs 9 cents/kWh. with concentration on part b. Thanks.

How long would it take in hours to administer exactly 400 mL of fluid through an IV with a drop factor of 20 gtt/mL if the drip rate is 70 gtt/min? Answer: 1.0 hour. Note: I just don't know on how it came up the answer is 1.9 per hours. Anyone plese explain it to me and show the solution please? Thank you for your help!

You have a 2.0-uF capacitor and a 9.0-V battery: 2a. If initially uncharged, how long does it take to charge the capacitor to 80% of its maximum voltage through a 1.5-M2 resistor? Assume its maximum voltage is the same as the battery. 2b. If initially fully charged, how long would it take to discharge the capacitor to 30% of its maximum voltage through a 2.4-MΩ resistor?
