- You are making banana bread and the recipe calls for 3/4 cup of vegetable oil and one egg yolk. You measure out your oil in a measuring cup and then just toss the egg yolk into the oil before mixing with the dry ingredients. The egg yolk has a mass of 9.9 grams and floats with 71 % of its volume under the surface of the oil. You also know that the density of the oil is Poil 0.95 cm³ What volume of oil is displaced by the egg yolk? cm3 What is the total volume of the egg yolk? cm³ What is the density of the egg yolk? g cm3 Imagine the egg yolk was floating in a salt-water solution instead (Pwater = 1.04 % .). What percentage of the yolk would be submerged in water? cm³The Earth's atmosphere at sea level and under normal conditions has a pressure of 1.01x105 Pa, which is due to the weight of the air above the ground pushing down on it. How much force due to this pressure is exerted on the roof of a building whose dimensions are 10.2 m long and 14.5 m wide?A company has several sensors in storage silos to detect the total pressure in the silos to ensure the tanks will not leak. Each tank is designed to withstand a maximum total pressure of 5.7 atmospheres [atm]. An engineer wants to use one of the silos to store liquid nitric acid, which has a density of 97 pound-mass per cubic foot [lbm/ft3]. If the tank is filled to a depth of 90 feet [ft], how much surface pressure in units of atmospheres [atm] can be applied to the top of the liquid inside the tank without exceeding the maximum total pressure of the silo?
- A large tub is filled with water, and it is found that the pressure at the bottom is 1) 1.12 x 105 Pa. The same tub is then filled with mercury. What is the new pressure at the bottom of the tub?What is the mass of a solid gold rectangular bar that has dimensions l x w x h = 5.60 cm ✕ 12.0 cm ✕ 25.0 cm? (The density of gold is 19.3e3 kg/m3. Don't forget to convert from centimeter to meter)At a given instant, the blood pressure in the heart is 1.1 x 104 Pa. If an artery in the brain is 0.38 m above the heart, what is the pressure in the artery? Ignore any pressure changes due to blood flow. Number Type your answer here Units Choose your answer here
- An automobile weighing 1.19 x 104 N has weight equally distributed over its wheels. The weight of the car causes each tire to be slightly flattened on the bottom so that there is a surface area in contact with the road. The gauge pressure of the air in the tire is 1.90 x 105 Pa (27.55 lb/in2). Find the area of contact, assuming that the only forces on the section of tire in contact with the road are the air pressure and the normal force exerted by the surface of the road. (The answer is not 0.06263 m2)A compressed gas with a total mass of 107 kg is stored in a spherical container having a radius of 0.521 m. What is the density of the compressed gas?Estimate the average blood pressure in a person’s foot if the foot is 1.03 m below the aorta, where is the average blood pressure is 101 mmHg. For the purposes of this estimate, assume the blood isn’t flowing. The density of blood is 1060 kg/m^3. Give your answer in units of mmHg.
