Consider two uniform solid spheres where both have the same diameter, but one has twice themass of the other. Theratio of the larger moment of inertia to that of the smaller moment of inertia is
Three boxes rest side-by-side on a smooth, horizontal floor. Their masses are 5.0 kg, 3.0 kg, and 2.0 kg, with the 3.0-kg mass in the center. A force of 50 N pushes on the 5.0-kg mass, which pushes against the other two masses. What is the contact force between the 3.0-kg mass and the 2.0-kg mass?
A. Suppose that $126,000 is to be allocated for advertising, research, and investment in theratio 8:4:2. How much money will be allocated for each?
b. Electric Depot sells boxes of high efficiency light bulbs ($6 box) and switch plates ($12 each). In May, total sales were $42000. Customers bought 5 times as many boxes of l
When barium (Ba) reacts with sulfur (S) to form barium sulfide (BaS), each Ba atom reacts with an S atom. If 2.40 cm3 of Ba reacts with 1.65 cm3 of S, are there enough Ba atoms to react with the S atoms (d of Ba = 3.51 g/cm3; d of S = 2.07 g/cm3)?
For barium sulfide, calculate the barium to sulfur massratio.
