On a cool day at 21 °C on the beach Isabella wants to propose to her boyfriend, she has a sign that reads, "Will you marry me?". The sign weighs 21.2 lbs. To carry the sign into the air Isabella fills 2 balloons with Helium gas. How many liters of helium must Isabella fill each balloon with? (453.6 g = 1 lb) The buoyancy of He is the difference between the density of helium and the density of air (whose weighted average molar mass can be calculated from the gasses that make it up and their % (N₂ = 78%, O₂ = 21%, Ar = 1%). HINT: calculate the mass in grams Helium can lift. PS. Isabella realized that her non-science major boyfriend was not smart enough for her and dumped him!

A plane is fitted with pontoons for operation on lakes. As it taxies out for take-off, the plane itself weighs 10670 Newtons (2849lbs), it has 40 gallons of gasoline in its tanks, and the pilot and passenger together weigh 1513 Newtons (340 lbs). One gallon of gasoline weighs 25 Newtons (5.67lbs). What is buoyant force on the plane when it floats in a body of water? Take the mass density of water to be 1000 kg/m3 and the acceleration due to gravity as 9.8 m/s2
Q1/ The helium-filled blimp shown in Fig. A is used at various athletic events. Determine the number of pounds of helium within it if its volume is 1950 m and the temperature and pressure are 26 °C and 14.2 psia, respectively. Fig. A
H.W: A hypodermic syringe contains a medicine with the density of water. The barrel of the syringe has a cross-sectional area (2.50x10-5) m2, and the needle has a cross-sectional area (1.00x10 8 ) m². In the absence of a force on the plunger, the pressure everywhere is 1.00 atm. A force F of magnitude 2.00 N acts on the plunger, making medicine squirt horizontally from the needle. Determine the speed of the medicine as it leaves the needles tip.
The pressure and temperature of the vessel is 380 KPa and 60 degrees celcius, what is the density of air in kg/m3? (neat handwritten)
What is the altitude an airplane is flying if the measured air pressure is 640.12471304150 psf? Assume standard condition.
A balloon is filled with helium gas and released at the surface of the moon. Describe the motion of the balloon when released.
A 10cm x 10 cm x 10cm block of steel (ρsteel = 7900 kg/m3) is suspended from a spring scale. The scale is in Newtons. a. What is the scale reading if the block is in air? b. What is the scale reading after the block has been lowered into a beaker of water and is completely submerged?
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.
A balloon considered spherical is 30 feet in diameter. The surrounding air is at 60 degrees Fahrenheit and the barometer reads 29.60 inches of mercury. What gross load may the balloon lift if it is filled with (a) hydrogen at 70 degrees Fahrenheit and atmospheric pressure? (b) Helium at 70 degrees Fahrenheit and atmospheric pressure. Final answer:
Question 2 The figure below shows a closed tank that contains gasoline floating on water. Calculate the air pressure above the gasoline. Air Gasoline 0.50 m (sg = 0.68) Water 100 m 457 mm 381 mm Mercury (sg = 13.34)
A closed tin of height h contains air at atmospheric pressure. It floats vertically in water as shown below, with a depth k under water. Rust causes a small hole in the base and water leaks in slowly. Show that the tin floats in equilibrium again when the water has risen to fill a height h k/H+k, where H is the height of a water barometer.
