The check valve of the fuel pump closes to maintain the remaining pressure in the fuel line when the fuel pump is stopped.Group of answer choicesTrueFalse

The following illustration shows the fuel pump control circuit. For its operation, select the statement that is False.Group of answer choicesThe engine ECU turns on the circuit opening relay and the fuel pump operates while the ignition switch is at IG position.The STA signal is input in the engine ECU and the fuel pump operates while the ignition switch is at ST position.The NE signal is input in the engine ECU while the engine is running and the fuel pump operates continuously.If the engine is stalled, the fuel pump is stopped because the NE signal is not input in the engine ECU even if the ignition switch is at IG position.

You are required to design an automated water pump regulator for a large farm. The pump is required to draw water from a dam and store it in three tanks all connected to one another, while the regulator is responsible for automatically closing and opening the single valve that leads to the first tank. The tanks will only overflow when they are all full, so as long as one of them is not full, the valve must remain open. The valve is incorporated to prevent any possible overflow. For the design of the automated regulator, the following specifications have been provided:If the dam is not empty and any tank is not full, open the valve;If a tank is full but does not overflow, the valve must remain open;If any tank is full and starts to overflow, close the valve.Define and present the propositional logic variables needed to represent the conditions within these specifications, avoiding using negative propositions. So, for example, you cannot write P: "item is not state", you can write P: "item is state". You must create the minimum number of necessary propositional variables only.
