Why does an operational amplifier need a power supply?

It doesn't. You can make a differential amplifier with a single power supply.

Why is an operational amplifier called so?

Originally such an amplifier did mathematical functions.

Is operational amplifier is analog or digital?

analog device

What is the full form of OP-AMP?

operational amplifier

What are the values so that over all gain is 10 in instrumentation amplifier?

You need a divider that is 10 to 1. You could use 10 megohms in the feedback and 1 megohm in the bottom leg. Since you are probably talking about an operational amplifier, you need this in both legs.

What does gm0 represent in a BJT amplifier circuit?

gm0 is not used in BJT amplifier circuits; it is used in JFET circuits. It is the transconductance at zero gate bias. Since the transconductance varies as the bias is varied, this gives a benchmark level at a given defined point, and other transconductances can be calculated from it as a function of the amount of negative bias on the gate. If it were linear it would be the same everywhere, but it is not.
