Passage:
Deep-sea autonomous gliders adjust buoyancy rather than using motorized propellers to navigate through the water column. To descend, an internal pump transfers hydraulic fluid from a flexible external bladder into a rigid internal reservoir, reducing displacement and increasing overall vehicle density. To ascend, the pump forces the fluid back into the external bladder, expanding the vehicle's volume and decreasing density.
Based on the passage, if the hydraulic pump loses power while the fluid is fully contained within the internal reservoir, the glider will be unable to ascend to the surface on its own.
Cevap: Cevap
Cevap
True, because ascending requires active pumping to expand the external bladder and reduce vehicle density.
The conclusion logically follows from the text because ascent is entirely dependent on pumping fluid into the external bladder. Without electrical power to operate the pump and without alternative propulsion such as motorized propellers, the glider cannot decrease its density to rise.
