A cube of iron, which has a density of 7.87 g/cm3, has an edge length of 3.75 cm. What is the mass of the sample?
A pure copper cube has an edge length of 1.30 cm . Part A How many copper atoms does it contain? (volume of a cube = (edge length)3; density of copper = 8.96 g/cm3) N= Cu atoms
A cube made of platinum (Pt) has an edge length of 1.50 cm. The density of Pt is 21.45 g/cm3. (a) Calculate the number of Pt atoms in the cube. (b)Atoms are spherical in shape. Therefore, the Pt atoms in the cube cannot fill all the available space. If only 74.0 percent of the space inside the cube is taken up by Pt atoms, calculate the radius in picometers of a Pt atom. The mass of a single Pt atom...
A particle is located at each corner of an imaginary cube. Each edge of the cube is 0.528 m long, and each particle has a mass of 0.214 kg. What is the moment of inertia of these particles with respect to an axis that lies along one edge of the cube?

Question 7 (3 points) Choose the answer. The edge of a cube was found to have a length of 50 cm with a possible error in measurement of 0.1 cm. Based on the measurement, you determine that the volume is 125,000 cm3. Use tangent line approximation to estimate the percentage error in volume. 0.6% 0.9% 1.2% 1.5% 1.8% Previous Page Next Page Page 7 of 10 Submit Quiz 3 of 10 questions saved
