Derive Stokes’ law using the previously derived Newton’s Law for settling velocity of a particle
If a particle with 4-µm diameter and unknown density has a settling velocity of 0.1 cm/s in the air, then according to Stokes Law, another particle with the same diameter but half of the density will have a setting velocity of _____ cm/s (Assuming the density of air is negligible).
Derived Newton’s second law using constant acceleration ( Distance of Free-Fall) and find Work is equivalent to KE.
Starting with classical physics equations for kinetic energy, work and Newton’s second law derive an expression for kinetic energy that includes relativistic particle velocities. Derive Ek = mc2-moc2
Derive the ideal gas law from a particle moving with a velocity vx a rectangular box with dimensions Lx, Lyand Lz. a). Draw a picture of the system b). Drive the gas law.

mework 7 blem 11.79-Enhanced-with Hints and Feedback Determine the velocity of the particle at which Stokes' law becomes invalid, at about Re Express your answer to three significant figures and include the appropriate units Review A 2.3-mm-diameter sand particle having a density of 2.40 Mg/m3 is released from rest at the surface of oi that is contained in the tube. As the particle fails downward, "creeping flow' will be established around it. The oil has a density of...
Using Newton’s law of gravitation, find the centripetal acceleration of a satellite orbiting the Earth at a distance of R = 12×106 m. What is the angular velocity of that satellite? What is the period of motion? Earth’s mass: ME = 5.973×1024 kg Universal Gravitational constant: G = 6.674×10−11 m3kg−1s−2.
Determine the settling velocity (m/s) of a sand particle with a density of 2.6 g/cm3 and 1 mm diameter. νw = 1.307x10-6 m2/s and ρw = 998 kg/m3.
(10 pts) For quiescent (still water) conditions determine the settling velocity of spheres of four particle diameters: 0.01,0.1, 1.0, and 10.0 mm. Assume the particle density if 1,050 kg/m3. Plot vs versus dpon a log-log axis.
Stokes' law describes sedimentation of particles in liquids and can be used to measure viscosity. Particles in liquids achieve terminal velocity quickly. One can measure the time it takes for a particle to fall a certain distance and then use Stokes' law to calculate the viscosity of the liquid. Suppose a steel ball bearing (density 7.8 x 103 kg/m3, diameter 2.0 mm) is dropped in a container of motor oil. It takes 11 s to fall a distance of 0.65...
