One kind of e-book display consists of millions of very small spheres that float in a thin fluid layer between two conducting transparent plates. each sphere is black on one side and white on the other, and possesses an electric dipole moment directed from the white side to the black. When an electric field is applied between the plates, the spheres rotate so that their dipole moment lines up with the field. Depending on the fields direction, either the black or the white sides of th espheres can be made visible. The dipole moment of the spheres can be modeled as two opposite charges of magnitude 3.5 x 10^-15 C, separated by a distancce of 100 micrometers (um). What is the maximum possible torque on a sphere if the electric field between the transparent plates is 4.0 x 10^5 N/C

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)
