Two spheres P and Q for equal radii havedensities p₁ and P2, respectively. Thespheres are connected by a massless stringand placed in liquids L and L of densitieso₁ and ₂ and viscosities 1₁ and 1₂,respectively. They float in equilibriumwith the sphere P in L and sphere Q in L₂and the string being taut (see figure). Ifsphere P alone in L2 has terminal velocity vp and Q alone inL has terminal velocity vo,then|vp| _ n₁|v₂| M2(c) Vp Vo> 0(a)|Vpl_1₂|vp|vel ani(d) Vp Vo <0(b)L₁L₂2P

.We are aware that two spheres with similar radii, P and Q, have densities of ρ1 and ρ2,…

You are walking by a river flowing at 1.67 m/s and decide to step into it to cool off. (a) Estimate the force exerted on you as a function of the depth of the river. (b) What is the force on you if you lie in a swimming position, but remain stationary? (c) How does the force vary with the speed of the river? Hints: Treat your body as a cylinder, and take the density of the water to be 1000 kg/m³.

P Some fish have a density slightly less than that of water and must exert a force, by swimming, to stay barely submerged. What magnitude of force, in newtons, must an 82-5-kg grouper exert to stay submerged in salt water (with density 1025 kg/m³) if its body density is 1015 kg/m³?
While workers spray paint the ceiling of a room, numerous small paint aerosols are dispersed into the air. Eventually, these particles will settle out and fall to the floor or other surfaces. Consider small spherical paint particles of diameter D = 10 μm and specific gravity of 1.2. Determine the time it would take this particle to fall 2.4 m from near the ceiling to the floor. Assume that the air within the room is motionless.
