A doctor has a patient blow on one side of a U-shaped tube that is partially

filled with water and has a ball floating on the other side, as shown in the
image below. If the ball rises with a force of 200 N, what pressure did the
patient apply to his side of the tube?

Answer: 100,000 Pa

Step-by-step explanation:


$$Applied Force $=200 \mathrm{~N}$ \\Area $=0.002 \mathrm{~m}^(2)$\\\\Pressure $=\frac{\text { Force }}{\text { Area }}$\\$=(200)/(0.002)$\\$=(200)/(2 * 10^(-3))$\\$=100,000 \mathrm{~Pa}$
