How big is a million dollars? At the time this text was written, the price of gold was about $1400 per ounce, while that of silver was about $20 an ounce. The “ounce” in this case is the troy ounce, which is equal to 31.1035 g. (The more familiar avoirdupois ounce is equal to 28.35 g.) The density of gold is 19.3 g/cm3 and that of silver is 10.5 g/cm3. (a) If you found a spherical gold nugget worth $1 million, what would be its diameter? (b) How much would a silver nugget of that size be worth?

- A rod extending between x = 0 and x = 14.0 cm has uniform cross-sectional area A = 9.00 cm2. Its density increases steadily between its ends from 2.70 g/cm3 to 19.3 g/cm3. (a) Identify the constants B and C required in the expression = B + Cx to describe the variable density. (b) The mass of the rod is given by m=allmaterialdV=allxAdx=014.0cm(B+Cx)(9.00cm2)dx Carry out the integration to find the mass of the rod.arrow_forwardHow many cubic meters of helium are required to lift a light balloon with a 400-kg payload to a height of 8 000 m? Take Hc = 0.179 kg/m3. Assume the balloon maintains a constant volume and the density of air decreases with the altitude z according to the expression pair = 0e-z/8 000, where z is in meters and 0 = 1.20 kg/m3 is the density of air at sea level.arrow_forwardA 75.0-kg floats in freshwater 3.00% of his volume above water when his are empty, and 5.00% of his volume above water when his lungs are full. Calculate the volume of air inhales—called his lung capacity—in liters. (b) Does lung volume seem reasonable?arrow_forward
- Mercury is poured into a U-tube as shown in Figure P15.17a. The left arm of the tube has cross-sectional area A1 of 10.0 cm2, and the right arm has a cross-sectional area A2 of 5.00 cm2. One hundred grams of water are then poured into the right arm as shown in Figure P15.17b. (a) Determine the length of the water column in the right arm of the U-tube. (b) Given that the density of mercury is 13.6 g/cm3, what distance h does the mercury rise in the left arm?arrow_forwardAlloys of gold are rated in karats, a dimensionless unit that is used to indicate the proportion of gold by weight in a gold-containing alloy. If an alloy is one part in twenty-four pure gold, then it is classified as one karat gold. The density of gold is 19.3 x 10³ kg/m³. Determine the volume of gold in a 17.5 karat gold necklace that has a weight of 1.33 N. m³arrow_forwardAn artifact is dug out of the ground on a Greek Island and the archeologists want to determine the type of material it is made of. They have a meter, a scale, and a table of densities of known materials. They measure the three sides of the artifact to be 1.2 mm, 2.7 mm, and 3.4 mm and a mass of 6.7 g. What is the density of the amterial in kg/m^3?arrow_forward
- An empty food can has a mass of 64.87 grams. You fill it with 13.38mL of juice. The total mass of the can is 123.83grams what is the density of juice in g/L *(1L=1000cm^3)arrow_forwardAs an astute observer walking around on continental crust (granite), you might decide to test the hypothesis that the Earth is made entirely of granite. You weigh a 1.00 cubic ft piece of granite on your home scale and find that it weighs 171 lbs. Thus, you determine that the granite has a density of 171 lb/ft. Convert your granite's density to g/cm.arrow_forwardIron has a density of 7.874 g/cm3. What is the mass of a rectangular block of iron with dimensions of 3.000 cm by 4.000 cm by 5.000 cm?arrow_forward
- A straightforward method of finding the density of an object is to measure its mass and then measure its volume by submerging it in a graduated cylinder. What is the density (in g/cm3) of a 260 grock that displaces 75.0 cm3 of water? (Note that the accuracy and practical applications of this technique are more limited than a variety of others that are based on Archimedes' principle.) g/cm3arrow_forwardAn aluminum sphere has a diameter of 15.6 cm. What is its mass? (density of aluminum= 2700 kg/m3)arrow_forwardSolve the following problem. Round off the final answer to three decimal places. The density of silver is 10.50 g/cm^3. If 5.50 g of pure silver pellets are added to a graduated cylinder containing 11.0 mL of water, to what volume will the water in the cylinder rise?arrow_forward
