3. A washing machine contains the following input devices: - A switch S to turn the machine ON/OFF (1= on, 0=off) - A sensor D to check whether the door is closed ( 1= closed, 0= open) - A sensor L to check that the machine is loaded with clothes (1= loaded, 0= unloaded) The inputs are connected to a logic circuit shown below. The output of the circuit is connected to an electric motor (M) that controls the washing machine's drum. The motor turns ON when the logic circuit outputs is 1. a) What happens to the motor when switch S is OFF? b) What happens to the motor when the machine is ON and the door is closed? c) What happens if the user switches on an empty machine with the door open? d) Extend the logic circuit such to sound a beeper B (outputs 1) if the user tries to activate (S=1) a loaded machine with the door open. e) Draw another logic circuit that will activate a pump P (output 1) only if the switch is ON, the machine is loaded and the door is closed
