You haven't mentioned the voltage or the Amp-hour capacity of the battery.
In order to estimate the life of the battery, we need to know both of those,
and we also need to be assured that the battery voltage is the same as the
designed operating voltage of the appliance.

When an ammeter is connected in a circuit which terminal of the battery must be connected to the positive terminal of the ammeter?
The positive terminal of the battery would be connected to the positive terminal of the ammeter. The load would then be connected between the two negative terminals, positive side of the load being connected to the negative side of the ammeter.
What would be a basic electical circuit?
a battery and a resistor connected together.
What would happen if you connected the ends of a battery in a series circuit with wire?
You would short out the battery. If it was a car battery capable of 300 amps and the wire was big enough, the battery could explode.
A voltmeter is connected to the terminals of a battery that has emf 12.0V and internal resistance 3.00 ohms The battery is not connected to any other external circuitry What is the vmeter's reading?
The voltmeter would read 12 volts. An ammeter connected to to battery would only read 4 amps (12 volts divided by 3 ohms =4)
1966 mustang alternaltor smokes when battery is connected only smokes from wire coming from starter solenoid?
I am not completely sure on why you battery in your Mustang would be smoking only when connected to the starter. I would take into a shop and have them look at it.
What is the difference between short to Battery and Open Load?
Related to a battery and open load is the battery just sitting there without anything connected. A short is a very low resistance attached to the tow terminals of the battery. For example, a wire connected across the battery terminals would constitute a short.

Torch equals flashlight. Battery negative connected to case switched to bulbs outside. Positive connected to the lamps bottom. Called a series circuit.
If you connected a battery to a usb cord with some wire and connected that to another device would it charge?
depends on the voltage of the battery being used. USB voltage is 5 volts DC. If you use a car battery, which is generally 12 volts, I would think your device would not like this. But to answer your question. Yes, it will charge. But not properly if you do not use the correct voltage.
Suppose you wrapped an iron bar with wire and connected the ends of the wire to a battery what is this device called what would happen to this device if you disconnected the battery?
This would be an Electromagnet...... If the battery is disconnected, then the iron bar will become a permanent magnet.
