An object has a mass of 100 kg and a density of 10 g/cm3. What is the volume of the object in cm3?
Gold has a density of 19.3 g/cm3, and quartz has a density of 2.65 g/cm3. A sample of quartz contains gold. If the quartz sample has a mass of 10 g and a volume of 3 cm3, what is the mass in grams of gold in the quartz sample?
Sphere 1 (Area = A = 4 π r2, Volume = V = (4/3) π r3) has a radius of r1, and sphere 2 has a radius of r2= 2 * r1.
A: What is the ratio of the area of sphere 1 to sphere 2 (i.e., A1/A2)?
Sphere 1 (Area = A = 4 π r2, Volume = V = (4/3) π r3) has a radius of r1, and sphere 2 has a radius of r2= 2 * r1.
B: What is the ratio of the volume of sphere 1 to sphere 2 (i.e., V1/V2)?
A scale model of an object (m = 10 kg, A = 35 cm2, V = 40 cm3) is made such that the dimensions of the scale model are 5 times larger than the original object, but the scale model is identical to the object in every other way. Answer the following questions:
A: What is the mass mmodel in kg of the scale model?
