A small sphere of mass 9.20 10-5 kg and radius 7.40 10-4 m falls through a fluid of viscosity 0.36 kg/(m · s). Assume that the viscous force (or drag force) is given by Stokes' Law. (a) Calculate the viscous force (in N) when the sphere has a speed of 2.1 cm/s. (b) What is the terminal speed (in cm/s) of the sphere? cm/s

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...

QUESTION 1 A Mercedes-Benz 300SL, mass = 1,731 kg, is parked on a road that rises above the horizontal 11 degrees. What is the magnitude of the normal force in N with 3 significant figures? (acceleration due to gravity = g =9.80 m/s-, down) QUESTION 2 A Mercedes-Benz 300SL, mass = 1,683 kg, is parked on a road that rises above the horizontal 19 degrees. What is the magnitude of the static frictional force that the ground exerts on the...
