A stainless steel ball bearing has a radius of 6.35 mm and a denisity of 7.75 g/cm^3. Iron is the principle element in steel while carbon is a minor element. The ball bearing contains 0.25% carbon by mass. Assuming that the percent isotopic abundance for ^13 C is 1.108%, how many iron ^12 C and ^13 C are present in the ball bearing

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...

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 ✕ 103 kg/m3, diameter 3.2 mm) is dropped in a container of motor oil. It takes 11 s to fall a distance of 0.45...

1. A block of aluminum that has dimensions 1.16 cm by 3.00 cm by 5.00 cm is suspended by a thread from a spring scale. Density of aluminum is 2702 kg /m3. A beaker full of oil (density 8.50 × 105 g/cm3) rests on a second scale, which reads 460.0 g. The block is then lowered so it is fully submerged in oil without touching the bottom of the beaker. What is the reading on the spring scale supporting the...

Problem #3 At very low Reynolds numbers a ball viscometer can be used to measure fluid viscosity by dropping a spherical ball in the fluid and measuring its terminal velocity. Consider a solid ball of radius a = 1cm and density Ps = 2,500 kg/m falling in liquid glycerin with density P = 1,250 kg/m3. The measured terminal velocity of the ball is U = 0.15 m/s. Calculate the viscosity of the liquid.
