A lossless air spaced T-line having a characteristic impedance of 75 Ohms and 0.65 lamda in length is terminated in a load impedance of 75 – j90 ohm. Use the Smith Chart to find
• the input impedance of the load line combination
• the reflection coefficient (magnitude and phase angle) at the load
• the reflection coefficient (magnitude and phase angle) at the line input
• the SWR of the load-line combination
• the distance in wavelengths of the first voltage minimum away from the load
Clearly show all results and method on the smith chart.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?
