Module 15. Gas turbine engine
An exhaust cone placed aft of the turbine in a jet engine will cause the pressure in the first part of the exhaust duct to
•  increase and the velocity to decrease.
•  decrease and the velocity to increase.
•  increase and the velocity to increase.

Ekio asking:
•  The type of duct that forms the exhaust cone will determine what happens with the pressure and temperature. I distinguish 2 types of cone and therefore 2 types of conduit:

1 / convergent - divergent
2 / divergent

yeah but here it doesnt say for something specific.So take it as it is.Exhaust cone aft of the turbine,increases pressure decreases velocity.

the exhaust cone to maximize thrust has to increase efflux speed not pressure....
