1.) Find the terminal velocity (in m/s) of a spherical bacterium (diameter 1.94 µm) falling in water. You will first need to note that the drag force is equal to the weight at terminal velocity. Take the density of the bacterium to be 1.10 ✕ 103 kg/m3. (Assume the viscosity of water is 1.002 ✕ 10−3 kg/(m · s).
Please don't attempt if you can not write a MATLAB PROGRAM. I don't need numerical physics solution, I need MATLAB code. Read the question carefully 2) Falling Drops Imagine a solid sphere of diameter, d, falling through the air. After its release, the sphere accelerates until it reaches its terminal velocity. The terminal velocity is obtained when the drag force due to air friction, Fa, balances the weight of the sphere, W. The weight of the sphere is simply its...
in this lab we will drop a steel ball P steel=8000 kg/m^3, r ball=2.18x10^-3) through the air (nair=1.8x10^-5 Pas, P air= 1.29kg/m^3) and through a viscous soap solution (n soap ~ 9.0 Pa s) you will measure this number in lab, but use this number for prelab.( P soap = 1000kg/m^3) 1Pa= 1N/m 1. (a) assuming that the ball falling through the soap solution experiences visocus drag, find the terminal speed of the ball, the speed at which the weight...

One expression for the Reynolds number is Re-V,d V a. Since the Reynolds number must be dimensionless, what are the units of the v term in the denominator? b. Does the v term represent the kinematic or dynamic viscosity? C. Find...
Calculate the terminal velocity for a pollen grain falling through the air using the drag force equation. Assume the pollen grain has a diameter of 7 µm and a density of 0.3 g/cm3. If this grain is released from the top of a tree (height 11 m), estimate the time it will take to fall to the ground. Hint: The pollen grain will reach its terminal velocity very quickly and will have this velocity for essentially the entire motion. Your...
Part 1 How fast do small water droplets of 0.23 um (23 x 108 m) diameter fall through the air under standard sea-level conditions? Assume the drops do not evaporate. Repeat the problem for standard conditions at 5000-m altitude. (a) For the condition that the droplets are falling at a constant velocity, what is the relation between the weight ofa drop W, the buoyancy force Fe, and the drag force F? (b) What is the expression for the weight of...

The rolling resistance of steel is typically mu_r = .002. If a train weighing 160,000 kg is rolling at 12m/s and the engineer turns off the engine to let the train cruise to a stop, how much time will it take to come to a stop? How far will the train move during this time? What is the drag force on a 1.5 m wide, 1.8 m high car traveling at 20 m/s? A 22 cm diameter bowling ball has...
