An astronaut is working outside the International Space Station where the atmospheric pressure is essentially zero. The pressure gauge on her air tank reads 690000 Pa. What force does the air inside the tank exert on the flat end of the cylindrical tank, a disk 0.150 m in diameter?

Explanation:

Pressure = Force/Area

Given

Pressure = 690,000Pa

Area will be the area of the circular section of the cylindrical tank

Area of a circle =πd²/4

Area of a circle =π(0.15)²/4

Area of a circle = 3.14(0.0225)/4

Area of a circle = 0.07065/4

Area of a circle = 0.0176625m²

Get the force

Force = Pressure * Area

Force = 690,000* 0.0176625

Force = 12,187.125N

Hence the force applied by the air inside the tank is 12,187.125N

answer: its c lololo

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
