No.
Some AC motors are designed to start running as soon as electricity is provided. Other AC motors are designed for a specific purpose and do not start on AC current. They will RUN on AC, but require a DC current to start. Here's where the capacitor comes in. It stores DC power that, when released, starts the motor turning. At this point, AC current will nicely run the motor.

No, the pump runs on AC current the battery supplies DC current. Yes, but you will need an inverter to turn the DC current into AC current
I've never heard of a DC ceiling fan, but.. AC-Alternating current. Electricity flows through a circuit in one direction, then changes direction and goes back the other way. This happens 60 times per second in the US. (60Hz) The US power distribution system is AC. DC-Direct Current. Electricity flows through a circuit in only one direction continuously. Batteries powering a flashlight, for example, are DC. Well, all batteries are DC. Like I said, I've never heard of a DC ceiling fan, but the DC fan's motor is designed to run on DC (such as batteries) only, and the AC fan motor is designed to run on AC only. I have heard however of a solar powered attic ventilator, which would be a DC fan. If there is a DC ceiling fan, however, keep in mind it needs a power source, and you won't be able to hook it up to the electrical box in the ceiling. That box is AC. The power source for a DC ceiling fan is likely replaceable batteries or solar cells, neither of which will make for a very robust fan.
Yes, a rheostat can be used with both AC and DC currents. The rheostat's variable resistor can be adjusted to control the current flowing through a circuit, regardless of whether it is AC or DC.
DC, unless you run an extension cord.
A "Rectifier" converts AC current to pulsating DC current.
No ... AC means Alternating Current - DC means Direct Current. DC is used mostly for electronics and for voltages within our vehicles. AC is used for motors and for our household appliances and lamps.
AC means alternating current DC means direct current there is no polarity reversal
The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.
