Answer:
Exit velocity 
m/s.
Explanation:
Given:
At inlet:
Properties of steam at 100 bar and 600°C
At exit:Lets take exit velocity 
We know that if we know only one property inside the dome then we will find the other property by using steam property table.
Given that dryness or quality of steam at the exit of nozzle is 0.85 and pressure P=80 bar.So from steam table we can find the other properties.
Properties of saturated steam at 80 bar
So the enthalpy of steam at the exit of turbine
Now from first law for open system
In the case of adiabatic nozzle Q=0,W=0
m/s
So Exit velocity m/s.
The current will lag the voltage in AC circuit that contains both resistance and inductance.
Answer: C
Explanation
There is no inductance only circuits in reality.
The circuits containing inductance has also a lower amount of resistance.
The current flows in both resistance and inductance.
There is a drop in the total voltage in resistance and inductance giving rise to the voltage applied in the coil when connected in a series.
An example being inductance coil an AC circuit connected to both resistance and inductance in series.
From the vector diagram, this conclusion can be drawn.
