1). A large chunk of metal has a mass of 544.3 kg, and its volume is measured to be 0.0480 m3. (i). Find the metal’s mass density and weight density in SI unit.                                                     ii). What kind of metal is this?                                                                                                       (2). Will the mass density of metal be different on the moon than it is on Earth? What about the weight density?        Explain your answer.

Calculate the number of vacancies per cubic meter in iron at 880 °C. The energy for vacancy formation is 1.08 eV/atom. The density and atomic weight for Fe are 7.65 g/cm3 and 55.85 g/mol, respectively. Express your result in exponential form with 1 decimal place.

(c) A piece of Alloy has a measured mass of 0.075Kg in air and 0.062Kg when immersed in water (See the shown Figure). Find its volume and its density. Air Water Good luck

Find the circumference and the area of a circle with diameter 10 cm. Write your answers in terms of t, and be sure to include the correct units in your answers. (a) Circumference: 10 cm (b) Area:

Archimedes established his principle while investigating a suspected fraud in the construction of a crown. The crown was made from an alloy of gold and silver instead of pure gold. Assume that the volume of the alloy was the combined volumes of components (the density of gold is 19.3g⁄(cm^3 ), the density of silver is 10.5g⁄(cm^3 )). If the crown had a weight of 9.81 N in air and 9.10 N in pure water, what percentage of gold (by weight) was it?

You are given a sample of metal and asked to determine its specific heat. You weigh the sample and find that its weight is 28.5 N. You carefully add 12 BTU of heat energy to the sample and find that its temperature rises 24℃. What is the sample’s specific heat in kJ/(kg∙K)?

Find out the silk density in g/cc if the specific gravity of the fiber is given as 1.32. Provide your answer with two decimal positions and no unit. Answer:

3. Two immiscible liquids A and B are in a container. A 100-g object is dropped onto the container and the object is observed to be at the liquid-liquid interface with 47% of the object's volume in A and 53% in B. If the density of the object is 7.6 g/cm³, what are the densities of A and B.

1. Clouds can weigh thousands of pounds due to their liquid water content. Often this content is measured in grams per cubic meter (g/m³). Assume that a cumulus cloud occupies a volume of one cubic kilometer, and its liquid water content is 0.2 g/m³. (a) What is the volume of this cloud in cubic miles? (b) How much does the water in the cloud weigh in pounds? 2. A tank of oil has a mass of 3 0 slugs. (a) Determine its weight in pounds and in newtons at the earth's surface. (b) What would be its mass (in slugs) and its weight (in pounds) if located on the moon's surface where the gravitational attraction is approximately one-sixth that at the earth's surface? 3. If p is a pressure, V a velocity, and p a fluid density, what are the dimensions (in the MLT system) of (a) p/p, (b) pvp, and (c) p/pV²? 4. The viscosity of a certain fluid is 5 x 104 poise. Determine its viscosity in both SI and BG units. 5. Crude oil having a viscosity of 9.52 X 10 lb-s/ft2 is contained between parallel…
