When a solid moves vertically down a liquid at terminal velocity work done on it is zero but it's gravitational potential energy decreases HOW?

As you say, work is not being done on it and its kinetic energy is constant, but it is losing potential energy. In this case the potential energy loss is being dissipated into turbulence of the fluid, which is a mechanical form of energy, and perhaps some thermal heating due to friction.
A good question, made me think!

What does a parachute do to terminal velocity?
It decreases the terminal velocity of the parachutist.
Is Voltage with respect to negative terminal taken as positive or negative?
im not sure how clearly your phrasing your question, but when dealing with circuits potential difference (voltage) is max, and at the positive terminal its zero. it decreases as you go around the circuit. hope this helps
What is the terminal potential in the short-circuit?
in the case of short-circuit the current is maximum hence the terminal potential is becomes zero
Why is terminal velocity an example of balanced forces?
When terminal velocity is reached, the gravitational force is balanced with the force of resistance.
A battery has a difference in potential energy between the positive terminal and negative terminal which units express this difference in energy?
That's a difference in electrical potential, not potential energy.It's described in units of "volts".
What effect terminal velocity and air resistance have on a sky diver when he opens his parachute?
Air resistance increases and terminal velocity decreases when the parachute has opened.
In a 1.5V battery taking the negative terminal as 0.0V what is the electrical potential energy of an electron leaving the negative battery terminal?
Somebody is trying a trick question! The electron that comes out of the negative terminal has zero potential energy. With respect to the positive terminal it has -1.5V of electrical potential energy, and so does every other electron at 0.0V whether or not they came out of the battery.
The terminals of a diode are called the?
anode positive potential cathode negative potential
When gravitational forces and air resistance equalize on an object that is falling toward earth and the object stops accelerating its velocity is called?
In that case, the object is said to have achieved terminal speed.
Why terminal potential difference is decrease when current in the circuit is increased?
If the terminal voltage decreases when more current is drawn, that is due to the internal resistance of the power supply. Every power supply has a limit to how much current can be drawn. It is limited by the internal resistance and due to ohms law the more current drawn through a resistor, then the more voltage is produced across it. This is in opposition to the terminal voltage and is subtracted from it.
What is terminal PD?
A terminal potential difference is the potential difference appearing across the terminals of a voltage source, such as a battery or a generator, which varies according to the load supplied.When the battery or generator is off load (i.e. no load is connected to it), the terminal potential difference is equal to the electromotive force of that battery or generator.The terminal potential difference tends to decrease as the load current increases, due to a corresponding increase in the internal voltage drop of the battery or generator.
A battery has a difference in potential energy between the positive terminal and negative terminal which units express the difference?
Volts. Volts is another term for potential.
