Constants Part C Hot air balloons float in the air because of the difference in density between cold and hot air. Consider a balloon in which the mass of the pilot basket together with the mass of the balloon fabric and other equipment is mb. The volume of the hot air inside the balloon is Vi and the volume of the basket, fabric, and other equipment is V2. The absolute temperature of the cold air outside the balloon is T...

40. The atmospheric pressure (force per unit area) on a surface at an altitude z is due to the weight of the column of air situated above the surface. Therefore, the difference in air pressure p between the top and bottom of a cylindrical volume element of height Az and cross-section area A equals the weight of the air enclosed (density ρ times volume V-: ΑΔε times gravity g), per unit area: Let Δ、→0 to derive...

The Problem: Depress the equation r6r +100 1. Decomposing a cube: Consider a cube with side length (a) Suppose we break the side of the cube at an arbitrary point ryb. This cut triggers the decomposition of the cube into the 8 pieces you have with your manipulative. You will have a cube with side length y and a cube with side length b. Identify the other 6 solids in terms of their dimensions using y and b so that...
