Radioisotopes are used in a variety of manufacturing and testing techniques. Wearmeasurements can be made using the following method. An automobile engine isproduced using piston rings with a total mass of 100 g, which includes 9.4 mCi of 5°FEwhose half-life is 45 days. The engine is test-run for 2000 hours, after which the oil isdrained and its activity is measured. If the activity of the engine oil is 5.49 x 103decays/s.(b) What would be the activity in the piston after 0.112 grams has been worn off thepiston?

Given data: - The total mass of the piston ring is M = 100 g. The half life period is t1/2 = 45…

The tungsten filament of an incandescent light bulb has a temperature of approximately 3000 K. The emissivity of tungsten is approximately 1/3, and you may assume that it is independent of wavelength. To increase the efficiency of an incandescent bulb, would you want to raise or lower the temperature? (Some incandescent bulbs do attain slightly higher efficiency by using a different temperature.)
