Step 1
Let A(t) be the number of pounds of salt in the tank at time t. Since brine containing 3 pounds of salt per gallon is pumped into the tank at a rate of 6 gal/min, the rate of change of the amount of salt in the tank is given by: dA/dt = (3 pounds/gallon) * (6 Show moreā¦

A parallel-plate capacitor with an air gap has capacitance C0. It is connected to a battery with potential V0 that gives it charge Q0 and stored energy U0. After the capacitor is disconnected from the battery, a dielectric with constant Īŗ = 8 is inserted into the air gap, completely filling it. In terms of the initial values, find the new capacitance C, charge Q, potential V, and stored energy U. (For C, use the following as necessary: C0. For Q, use the following as necessary: Q0. For V, use the following as necessary: V0. For U, use the following as necessary: U0.)

Please answer the following question, all parts, thank you. A. When a light bulb is connected to a 12-volt battery, the current of 0.3 A flows through it. When the same light bulb is connected to a 6-V battery, the current through the light bulb will be about: B. You need 64 J of work to push a 4-C charge from point A to point B in an electric field. What is the voltage between these two points? C. A 32-volt battery supplies a light bulb with 144 J of energy each second. Find the current that flows through the light bulb. D. An electric appliance draws 3600 C of charge each minute when connected to a 90-V battery. What current passes through the appliance? E. A parallel plate capacitor with air between its plates has a capacitance of 3 pF. Then, the distance between the plates is decreased 4 times and a dielectric with a dielectric constant of 1.8 is inserted to fill the space between the plates. The new capacitance is about:
