You can obtain a rough estimate of the size of a molecule by the following simple experiment. Let a droplet of oil spread out on a smooth surface of water. The resulting oil slick will be approximately one molecule thick. Given an oil droplet of mass 12.00 ✕ 10-7 kg and density 878 kg/m3 that spreads out into a circle of radius 41.8 cm on the water surface, what is the order of magnitude of the diameter of an oil...

2 A paint sprayer pumps air through a constriction in a 0.025- m diameter pipe, as shown in the figure. The flow causes the pressure in the constricted area to drop and paint rises up the feed tube and enters the air stream. The speed of the air stream in the 0.025-m diameter sections is 5.00 m/s. The density of the air is 1.29 kg/m3, and the density of the paint is 1200 kg/m3. We can treat the...

A spherical navigation buoy is tethered to the lake floor by a vertical cable(Figure 1). The outside diameter of the buoy is 1.00 m. The interior of the buoy consists of an aluminum shell 1.0 cm thick, and the rest is solid plastic. The density of aluminum is 2700 kg/m3 and the density of the plastic is 210 kg/m3 . The buoy is set to float exactly halfway out of the water. Determine the tension in the cable.
