Scientists are working on a new technique to kill cancer cells by zapping them with ultrahigh-energy (in the range of 1012 w) pulses of electromagnetic waves 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 4.0 μm in diameter, with the pulse lasting for 5.0 ns with an average power of 1.59×1012 w . we shall assume that the energy is spread uniformly over the faces of 100 cells for each pulse. a. how much energy is given to the cell during this pulse? u=. what is the intensity (in w/m^2) delivered tothe cell? i=/m^2c. what is the maximum value of the electric field in the pulse? emax=/md. what is the maximum value of the magnetic field in the pulse? bmax=
