- On a very stormy day, the pressure of a mercury barometer is 0.939 bar. What is the height of the mercury in the barometer?A cube of some unknown substance is held submerged in water. The cube has a mass of 0.540 kg and a volume of 0.000770 .What is the acceleration of the cube when it is released?You fill a balloon with helium and let it go. It floats up into the air, where it is essentially floating in a pool of air. Why does the helium filled balloon float in air? Make sure you use the words ‘buoyancy’, ‘density’ and ‘volume of displaced ‘air’ in answering this question.
- You have a tube where water enters at a velocity of 10.0 m/s, ascends 5.0 m, and then exits. The pressure pushes the water in at 250 kPa, and is measured come out at 150 kPa. The outcoming water is, faster than the incoming water. slower than the incoming water. the same speed as the incoming water.On a particle level, what two factors contribute to an increase in pressure in a constant volume closed vessel when temperature is raised? (Choose 2 answers.) particles hit the walls of the container with more force particles hit the walls of the container less often particles hit the walls of the container more often particles hit each other more often particles hit the walls of the container with less forceWater flows at 0.25 L/sL/s through a 7.0-mm-long garden hose 2.5 cmcm in diameter that is lying flat on the ground. The temperature of the water is 20 ∘C∘C. What is the gauge pressure of the water where it enters the hose? Express your answer in pascals.
