Calculate the density of the metal, and determine if the pin was made from brass (density 8.5 g/cm3), 14-karat gold (density 15 g/cm3), or 18 karat gold (density 17 g/cm3). 14. The planet Jupiter is often referred to as a “failed star” because its density, 1.33 g/cm3, is about that of our sun.

In Raiders of the Lost Ark, Indiana Jones tried to remove a gold idol from a booby-trapped pedestal. He replaces the idol with a bag of sand. If the idol has a mass of 2.00 kg, how many litres of sand must he place on the pedestal to keep the mass sensitive booby-trap from activating? (Density of sand is 3.00 g/cm3) Dimensional Analysis ...

II. Comparison of simple conversion operations in the English (customary) and Metric systems - Notice the unusual numbers relating the various units in the English system and the simplicity of the powers of ten in Metric. (An English-Metric conversion table is contained in the Appendix of Lutgens and Tarbuck, 2014). ENGLISH SYSTEM METRIC SYSTEM. 1.

Conversion of temperatures between Celsius and Fahrenheit scales is particularly problematic. • Students tend to equate density with mass. ... • Students often either round off too soon in calculations or they report the result to as many figures as their calculators produce.

1. Begin by explaining that density is a characteristic property of matter: different substances exhibit different densities. Density is defined as the mass of a substance divided by its volume. Tell the students that in the lab, they will determine the densities of water, antifreeze, and various solutions of antifreeze and water. Procedure. 1.

GT40P port = 4.8” CL & 140cc . 140/4.8 = 29.17 / 16.387 = 1.78 ci The derivation of the formula I am providing for this requires you to find the reciprocal, but scientific calculators have that function S / 360 x B area / (380 ft/sec x P area ) = 1/rpm = 6,462. 2.75 / 360 x 12.56 /(297 ft/sec x 1.78) = 1/rpm = 5,510
