Zorluk: ZorDrawing Logical Conclusions

Read the following passage:

Deep-sea Autonomous Underwater Vehicles (AUVs) rely on syntactic foam blocks made of hollow glass microspheres embedded in an epoxy resin matrix to maintain passive buoyancy. Under repeated cyclic dives to extreme depths, micro-fissures develop within the resin, allowing ambient seawater to seep into the internal interstitial spaces without rupturing the hollow microspheres. Because the overall external volume of the foam module does not change during this process, the gross volume of seawater displaced remains constant throughout the dive.

Based on the passage, evaluate whether the following statement is True or False:
An AUV that has developed interstitial seawater seepage will experience a decrease in net upward buoyant force compared to an undamaged vehicle operating at the same depth.

Cevap: Cevap

Cevap

True
The conclusion logically follows from the two core facts presented in the passage: the displaced volume stays identical, while internal water infiltration introduces additional mass, inevitably diminishing the vehicle's net upward force.

Adım Adım Çözüm

1
Analyze the conditions affecting upward buoyant force stated in the passage.
The external dimensions and displaced water volume remain completely constant.
Buoyancy depends directly on the volume of fluid displaced by the exterior surface of the body.
2
Analyze the internal physical changes occurring within the syntactic foam matrix.
Seawater infiltrates the micro-cracks in the resin, filling previously empty interstitial voids.
Water entering internal voids adds mass and downward gravitational pull without increasing displaced volume.
3
Synthesize the net force outcome from constant displacement and increased mass.
With upward displacement force constant and downward gravitational weight increased, net upward buoyancy decreases.
Deducing net physical equilibrium requires combining upward buoyant force and total systemic mass.
