Infra-red detectors, Physics

Part A) Infra-Red (IR) Detectors:

An IR detector has an impedance of Z= (400+j200) ? . .

During design tests the detector current is measured as 4 µA.

What is the output voltage of the detector?

Part B) Optic lens:

Using a converging lens of focal length f= 10 cm, we want an object to appear on the screen twice as big as its original size.

Where is the object to be located in front of the screen (real image)?
