Use MATLAB to record 10 seconds of your speech using a sampling frequency of 8000Hz(see: audiorecorder in MATLAB and record in Octave). Explain what is happening atthe hardware level when you record your speech (a continuous signal) to store it in yourcomputer (i. e., explain the steps involved in the sampling and quantization process).

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
