0,4 μm à 0,75 μm

> 0,75 μm

The given answer "> 0,75 μm" suggests that the wavelength of infrared rayon is greater than 0,75 μm. Infrared rays have longer wavelengths than visible light, and wavelengths greater than 0,75 μm fall within the infrared spectrum. Therefore, this answer indicates that the given rayon is emitting infrared radiation with a wavelength greater than 0,75 μm.

1 tours 15 %

4 tours 25 %

3 tours 10 %

2 tours , 20 %

The correct answer is 2 tours, 20%. The explanation for this answer is that the main control valve switches (nozzles) should be adjusted to operate after a maximum of 2 turns of the handle or when the valve stem has rotated 20% relative to its normal open position. This means that the valve should start functioning after the handle has been turned 2 times or when the valve stem has rotated 20% from its fully open position.

58. La chambre à retardement à normalement une capacité de

1 gallon

2 gallon

5 gallon

10 gallon

The correct answer is 2 gallon. A "chambre à retardement" is a French term that translates to "delay chamber" in English. It is commonly used in the context of engines and combustion processes. The capacity of a delay chamber is typically measured in gallons and refers to the volume of fuel and air mixture that can be stored before it is ignited. In this case, the delay chamber has a capacity of 2 gallons, meaning it can hold 2 gallons of the fuel and air mixture before ignition.

76. Circuit ______ : pour que le système entre en fonction, ça prend une détection sur les deux circuits que compose l'installation. Donc, une détection sur le détecteur 1 qui est sur le circuit A et une détection sur le détecteur 2 qui est sur le circuit B. ensuite, les phases 1 et 2 entre en fonction comme dans un circuit double. Ce système évite donc les déversements accidentels.

The correct answer is "croisé" because the passage describes a circuit that requires detection on both circuit A and circuit B in order for the system to function. This implies that the two circuits are connected or "crossed" in some way, allowing both phases 1 and 2 to function together like in a double circuit. This system helps prevent accidental spills.
