Answer:
Está incompleto, falta más
The teardrop could be an example as it was designed for that purpose, and most notably planes and such aero traveling vehicles
Question:
A cork floats on the surface of an incompressible liquid in a container exposed to atmospheric pressure. The container is then sealed and the air above the liquid is evacuated. The cork:
A. sinks slightly
B. rises slightly
C. floats at the same height
D. bobs up and down about its old position
Answer:
The correct answer is C) floats at the same height
Explanation:
The liquid is incompressible because its density very high and leaves no room for further compaction whether or not there is atmospheric pressure. So when you put a cork on the liquid, pressure or no pressure, there is no displacement hence it floats on the same height regardless of the absence of air.

Explanation:
it is correct because that is what
Power = (work done) / (time to do the work)
Power = (2000 J) / (5 sec)
<em>Power = 400 watts</em>
