You obsereve two spheres free-falling at the same velocity down a tube of fluid with density 0.87 g/cm^3. You know that one sphere is aluminum (2.71 g/cm^3) and the other is a 2 mm glass bead (2.2 g/cm^3).

A)What is the size of the aluminum sphere?

B)If it takes 50 seconds for the two spheres to travel 1m down the tube, what is the viscocity of the fluid?

C)What flow Regime is applicable to the system?

1.). Two sinusoidal waves are moving through a medium in the same direction, both having amplitudes of 4.00 cm, a wavelength of 3.50 m, and a period of 6.25 s, but one has a phase shift of an angle φ. What is the phase shift (in rad) if the resultant wave has an amplitude of 4.00 cm? Hint: Use the trig identity 2.). Consider two sinusoidal sine waves traveling along a string, modeled as y1(x, t) = (0.2 m)sin[(6 m−1)x...

Lab 9 – Molecular Biology In this lab, you will prepare an agarose gel and use gel electrophoresis to compare the size of 2 dye molecules Methyl orange and Ponceau G. You will also analyze an “unknown” sample that contains a mixture of two dyes. Dye molecules with lower molecular weight or greater electrical charge will migrate faster through the gel, than dye molecules with greater molecular weights or lesser electrical charge.
