Chapter 1, Problem 1.64E

Wire often sold in pounds spools according to the wire gauge number. That number refers to the diameter of the wire. How many meters are in 10 pound spool of 12 gauge aluminum wire? A 12 gauge wire has a diameter of 0.0808 inches. Aluminum has a density of 2.70g/cm^3

Calculate and record the average density of a penny (in g/mL) that is made after 1982. 95 percent copper and 5 percent zinc made up the composition of pennies before 1982.

1) The weight of a rock is measured to be 0.075 lbs. After placing the rock in a graduated cylinder containing 17.09 mL of water, the new measurement is 28.76 mL. Calculate the density of the rock in g/mL. 2) A person measures the velocity of a biker riding in a straight line along a sidewalk using a stopwatch. The time it took for the biker to pass 29 squares on the sidewalk was 11.29 seconds. The area of the squares on the sidewalk was measured to be 2731 in2. Calculate the velocity of the biker in m/s.Note: 1 in = 2.54 cm 3) A hollow square metal tube has a measurement of 1.98 in for each side and a weight of 60.92 g. The volume of empty space inside the tube was measured to be 2.44 in3. If the density of the metal used in constructing the tube is 11.46 g/mL, calculate the length of the tube in inches.Note: 1 in = 2.54 cm, 1 cm3 = 1 mL 4) Porosity is a measure of the void or empty spaces in a material and is a fraction of the volume of voids over the total volume. The density of the…
