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!
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.
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
what volume of water do the pontoons displace?
