(a) The equipment shown in the diagram was used by a student to investigate the variation with volume, of the pressure p of air, at constant temperature. The air was trapped in a tube of constant cross-sectional area above a column of oil. scale air- H pressure gauge oil- to air pump valve The pump forces oil to move up the tube decreasing the volume of the trapped air. The student measured the height H of the air column and the corresponding air pressure p. After each reduction in the volume the student waited for some time before measuring the pressure. Outline why this was necessary.

Strictly don't use chatgpt,i need solution in handwritten format. Read the question carefully. The container shown in the figure below contains water. (relative density =1.0), oil (ρ=800kg/m³) and air (ρ=1.2kg/m³). Knowing that the local atmospheric pressure is 105 Pa and that the local acceleration due to gravity is 10 m/s², the pressure gauge at the bottom of the oil column will be (in Pa): answer: 26000Pa Mechanical engineering

QUESTION 35 A syringe (X), forces air, at a high velocity, over a straw (Y). The air in the water chamber (Z) is not moving. Using Bernoulli's Principal, pick the best answer, that describes what will happen to the water in the chamber. Remember that things are always pushed from high pressure areas to low pressure areas. a. The high velocity air at (Y) will have the SAME PRESSURE as the low velocity air over the water at poing (Z), so the water will neither move up or down the straw. b. none of these are true. c. The water in the straw will be forced down into the chamber because the high velocity air at (Y) has a HIGH PRESSURE compared to the air over the water in the chamber at point (Z). d. The high velocity air at point (Y) will have a LOW PRESSURE. As a result, the slow air in the chamber (Z) will have a high pressure, thus forcing water up the straw.

A child takes a helium balloon on a plane from Denver (with an air pressure of 0.83 atm) on a cool day when the temperature is 20.0oC to Boston (at sea level, with an air pressure of 1.0 atm) where the temperature is 5.0oC. Assume that no gas escapes from the balloon during the flight. What is the volume of the balloon in Boston, relative to its size in Denver? Group of answer choices The volume in Boston is 0.79 times the volume in Denver. The volume in Boston is 0.20 times the volume in Denver. The volume in Boston is 0.87 times the volume in Denver The volume in Boston is 1.3 times the volume in Denver. The volume in Boston is the same as the volume in Denver.
