An underwater sensor housing is positioned near a hydrothermal vent at the ocean floor.
The hydrostatic pressure of the ocean water acting on the outside of the housing is 5.45 × 106 Pa.
The inert gas pressure inside the sealed electronics compartment of the housing is 1.02 × 105 Pa.
Calculate the pressure difference between the outside and the inside of the sensor housing.
