Gold, which has a density of 19.32 g/cm³, is the most ductile metal and can be pressed into a thin leaf or drawn out into a long fiber. (a)
If a sample of gold with a mass of 5.013 g, is pressed into a leaf of 8.428 μm thickness, what is the area of the leaf? (b) If, instead, the
gold is drawn out into a cylindrical fiber of radius 2.600 µm, what is the length of the fiber?

Physicians use a machine called a spirometer to measure the maximum amount of air a person can exhale (called the forced vital capacity). Suppose you can exhale 4.0L. How many kilograms of air do you exhale? Assume that the density of air is 1.3 kg/m3.
A uniform density sheet of metal is cut into the shape of an isosceles triangle, which is oriented with the base at the bottom and a corner at the top. It has a base B = 49 cm, height H = 15 cm, and area mass density σ. a) Consider a horizontal slice of the triangle that is a distance y from the top of the triangle and has a thickness dy. Write an equation for the area of this slice in terms of the distance y, and the base B and height H of the triangle. b) Set up an integral to calculate the vertical center of mass of the triangle, assuming it will have the form C ∫ f(y) where C has all the constants in it and f(y) is a function of y. What is f(y)? c)Integrate to find an equation for the location of the center of mass in the vertical direction. Use the coordinate system specified in the previous parts, with the origin at the top and positive downward. d)Find the numeric value for the distance between the top of the triangle and the center of mass in cm.
An accomplished silversmith needs an extremely thin sheet of silver. If he starts with a 3.70-kg sheet of silver, and pounds it to a thickness of 5.00 10-7 m (a small fraction of the thickness of a sheet of paper), determine the area of the sheet he has formed. Use 10.1 ⨯ 103 kg/m3 as the density of silver.
One mole of Gold (Au) atom has a mass of 197 g. We know that the density of gold is 19.30 g/cm3 in room temperature. Using those numbers, answer the following questions: a) What is the mass of a single gold atom in kg? b) Assume that gold atoms sit in a perfect cubic crystal structure. Estimate the distance between two gold atoms in meters. c) If we have a gold cube of 6 cm on each side, how many atoms can we fit along the edge of each side of the cube? d) What would be the mass, in kilograms, of the gold cube we discussed in part (c) (measuring 6 cm on each side)?

In 1923, the United States Army (there was no United States Air Force at that time) set a record for in-flight refueling of airplanes. Using two refueling planes, an Airco DH-4B biplane was able to remain in flight for 38 h. During the flight, the refueling planes were able to air-transfer a total of 687 gallons of fuel to the plane in 9 refueling transfers. Assume that the refueling nozzle had a diameter of 1.35 in and each refueling took 2.47 min to perform. Calculate the velocity of the fuel through the nozzle. Assume that the fuel filled the entire cross-sectional area of the nozzle. 22.82 velocity: m/s Incorrect

There are three cylindrical vases on the table, none of them is taller than 40 cm. The firstvase can be filled with 2 dl of water, the second one with 3 dl, and the third with more than 6 dl water. The area of the cross section of the first vase is 10 cm^2, the area of the cross section of the other two vases is 20 cm^2. There is the same amount (volume) of water in each vase. It can be observed that if a specific tuning fork is placed just above the vases, its sound is getting louder. The width of the bottom of each vase is 1 cm, the speed of sound in air is 340 m/s, and the frequency of the tuning fork is less than 1 kHz. a) What is the volume of water in the vases? b) What is the frequency of the tuning fork? c) What is the height of the third vase?
