When air expands adiabatically (without gaining or losing heat), its pressure P and volume V are related by the equation PV^1.4 =C where C is a constant. Suppose that at a certain instant the volume is 570 cubic centimeters and the pressure is 91 kPa and is decreasing at a rate of 13 kPa/minute. At what rate in cubic centimeters per minute is the volume increasing at
this instant?
(Pa stands for Pascal – it is equivalent to one Newton/(meter
squared); kPa is a kiloPascal or 1000 Pascals. )

Are all modern solid state electronics susceptible to EMP?

Do they have to be on, having electricity circulating in the ciruit at the time of EMP burst in order to be affected?

If a computer is not turned and is disconnected from the power outlet, with only its cmos battery power, will it be affected by EMP?

Will a regular portable radio without the battery in be affected? Or do I need to store it in a Faraday cage?
