- What is the total pressure at a depth of 580 m in a lake? (pw = 1.00 x 103 kg/m³, Po = 1.01 x 105 Pa) 6.99 x 10^6 Pa 9.10 x 10^6 Pa 7.16 x 10^6 Pa O 5.79 x 10^6 Pa1. Yves is trying to measure the pressure acting on a square platform. He has placed a mass of 30 kg on the disk and he measures the length of one side of the square as 20 cm. What is the pressure Yves should measure? (Hint: To calculate the area of the square platform, first convert the side () to meters and then use the following equation A 12)E15. Water emerges from a faucet at a speed of 1.5 m/s. After falling a short distance, its speed increases to 3 m/s as a result of the gravitational acceleration. By what number now would you multiply the original cross-sectional area of the stream to find the area at the lower position?hoto
- Find the absolute pressure of a diver under 66 m of sea level (?=1025 ??/?^3 ), and the atmospheric pressure at sea level is 101305 Pa?Barometric Pressure Halley's law states that the barometric pressure (in inches of mercury) at an altitude of x mi above sea level is approximated by the equation below. p(x) = 29.92e-0.2x (x 2 0) If the barometric pressure as measured by a hot-air balloonist is 20.5 in. of mercury, what is the balloonist's altitude? (Round your answer to two decimal places.)In NCAA softball, the softball is a sphere with a circumference between 11.88 and 12.13 inches [in] and a mass between 177 and 198 grams [g). You find a ball and determine the mass is 180 grams [g] and the specific gravity is 0.32. While this specific gravity seems low for a solid, the ball is not made of a completely solid material but is instead filled with a sponge-like substance. Determine the radius of the ball you found and report the value in units of inches [in]. Click the icon to view the table of common derived units in the SI system.
