. Ecosystems, political systems, and financial systems all have what in common with the systems engineer’s study?

They are technological in nature.

They are investigated using systems thinking.

They contain subsystems in different ways.

They demand complex energy inputs.

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
