Water in a tank is 2 m deep. What pressure does the water produce at the bottom (density 1,000 kg per cubic metre, g = 10 m/s2)?
Answer and explanation
Correct answer: A. 20,000 Pa
- Step 1: Pressure = density x g x depth. Step 2. 1,000 x 10 x 2 = 20,000 Pa. Answer: 20,000 Pa. Why not the others: these values slip a decimal or use the wrong depth.
