Scientists are working on a new technique to kill cancer cells by zapping them with ultrahigh-energy (in the range of 1.00×1012 W) pulses of light that last for an extremely short time (a few nanoseconds). These short pulses scramble the interior of a cell without causing it to explode, as long pulses would do. We can model a typical such cell as a disk 5.00 μm in diameter, with the pulse lasting for 4.00 ns with an average power of 2.00×1012 W. We shall assume that the energy is spread uniformly over the faces of 100 cells for each pulse.

A distant galaxy is simultaneously rotating and receding from the earth. As the drawing shows, the galactic center is receding from th earth at a relative speed of ug = 2.0000 × 106 m/s. Relative to the center, the tangential speed is v† = 0.4600 × 106 m/s for locations A and B, which are equidistant from the center.
