The densities of several common metals are listed below. Compare your experimental density with the given values and try to determine which metal you tested.

1 The densities of several common metals are listed below. Compare your experimental density with the given values and try to determine which metal you tested. What other properties could be used to help identify your metal? 2 Osmium metal, the densest element, has a density of 2.6 g/mL, while hydrogen, the least dense element, has a density of 8.99 times 10^-5 g/mL. Calculate volume occupied by 1.00 g of each element. How many times more dense is osmium than...

Determine the temperature rise in the specimen for each case in Problem 6.75 (Open-die forging of a cylindrical, annealed copper specimen 10 mm high and 25 mm in diameter, up to a reduction of 50%, for the cases of (a) no friction between the flat dies and the specimen, (b) ? = 0.10, and (c) ? = 0.30. Ignore barreling.), assuming that the process is adiabatic and the temperature is uniform throughout the specimen. Given: K=315 MPa; n=0.54 from table...

3.32. Quality Control. An automatic machine in a small factory produces metal parts. Most of the time (90% according to long-term records), it produces 95% good parts, while the remaining parts have to be scrapped. Other times, the machine slips into a less productive mode and only produces 70% good parts. The foreman observes the quality of parts that are produced by the machine and wants to stop and adjust the machine when she believes that the machine is not...

To try to determine whether the composition of the earth’s atmosphere has changed over time, scientists can examine the gas in bubbles trapped inside ancient amber. (That’s the plot of Jurassic Park.) Assume that the following 9 measures are a random sample from the late Cretaceous era (75 to 95 million years ago). The data represent the percent of nitrogen in each sample. 63.4 65.0 64.4 63.3 54.8 64.5 60.8 49.1 51.0 You asked to conduct a hypothesis test to determine whether the mean is less than 61. 1....
