Assume the density of the air is 1.2 1.2 kg/m3. How much energy does the truck lose to air resistance per hour? Give your answer in units of MJ (megajoules). 2.An unknown object is placed inside of a spherical container and dropped from an airplane. When...
2. A small spherical particle (diameter = 75x10-6 m) is falling through air from a high elevation. Density of air is 0.85 kg/m3 and viscosity is 1.47 x 10-5 kg/m.s. Density of particle is 1,500 kg/m3. Determine the terminal velocity of the particle. (10%)
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).
1) As a raindrop falls through the atmosphere, its speed initially changes as it falls toward the Earth. Before the raindrop reaches its terminal speed, the magnitude of its acceleration A. increases B. decreases C. stays constant at zero D. stays constant at 9.8 m/s? E. stays constant at a value not equal to zero nor 9.8 m/s2 The position vector of a particle is given by r(t) = 2tî + 3t2ġ where ř is measured in metres and t...
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...
