It is well known that you can trap water in a drinking straw by placing the tip of your finger over the top while the straw is in the water, and then lifting it out. The inner diameter of the straw is 0.5 cm; the height of the trapped water column inside the straw is 5.0 cm. Find the pressure in the air pocket between your finger and the water
1. Try this, if you haven't before: Place your finger tightly over the top of the straw, and lift the straw up out of the water. You should find that the water stays in the straw. a. What is the net force on the water in the straw? b. Draw a free body diagram for a system that is the water. c. Is the gas pressure inside the straw, between the liquid and your finger, greater than, less than, or...
Please see the Lab 9 Pre-Lab Tutorial on the Canvas page for CHM 210 Lab for a more detailed explanation of the concepts in pre-lab question 3. 3. Consider the two gas-collection apparatuses pictured below. In each case, as is trapped in the upper part of the inverted us-collection tube and water fills the lower part of the tube. keeping the gas sealed inside the tube. a. Identify which apparatus pictured below shows a trapped gas sample with pressure greater...
Could you please help me solve this problem with the step by step procedure to the solution.Could you also provide some key points that might help me understand the problem even more. Thank you! Question No.1.(20 marks) Air flows steadily and isentropically from atmospheric conditions (P"101.3 kPa absolute, ?-1.2 kg/m.

Write neat please. Show step by step please. Read instructions carefully. do all problems please. double check your work. Box in answer please. Thank you Question 17 1 pts A metal block has a mass of 5 grams and a volume of 1 cubic centimeter. A piece of the same kind of metal with a volume of 2 cubic centimeters has a density 2.5 g/cc. 5 g/cc. 10 g/cc. Question 18 1 pts Ice cubes submerged at the bottom of...
Mass of Magnesium strip Use the length of your magnesium strip and the mass per m provided by your TA to calculate the mass of your magnesium strip. Make sure to convert so that your units match! Mass of magnesium strip Moles of magnesium used Convert the mass of each magnesium strip into moles using the molar mass. Moles of magnesium Moles of hydrogen produced (n) Use the mole ratio from the balanced chemical equation to convert the moles magnesium...
please explain the reasoning behind each step as well. thank you A combined power cycle relies on a gas turbine cycle and a Rankine cycle. Heat is fed to the gas turbine combustor at a rate of 50 MW. The gas turbine cycle operates at an efficiency of 0.35. The gas that exhausts from the turbine is still hot and is used to boil water in the Rankine cycle. The Rankine cycle operates at an efficiency of 0.42. Find: a)...
1 2 Please solve for both, Thanks. A swimming pool measures a length of 5.3 m, width 3.8 m, and depth 3.1 m Part A Compute the force exerted by the water against the bottom.

Can you please help me with question 2a-c in step-by-step explanation. I did poorly on this question. 2. (10 points) A 6 cm3 ce cube is floating in a glass of water. The glass has a cross-sectional area of 50 cm and it is filled with water to a height of 12 cm. Ice has a density of pice 917 kg/m a. Calculate the magnitude of the buoyant force on the ice cube n'y loon m b. Find the percentage...
4. How can you solve for the density of the liquid from the slope? Please show your steps. 5. Predict how the buoyant force would differ for different liquids, like water vs. oil. 6. Write down the formula for the volume of a cylinder AND the area of a circle below.
