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.
