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 4.6 μm in diameter, with the pulse lasting for 3.4 ns with an average power of 2.46×1012 w . we shall assume that the energy is spread uniformly over the faces of 100 cells for each pulse.
part a
how much energy is given to the cell during the pulse?

According to your data, was your hypothesis correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. list at least two real world examples that apply the findings of this experiment. (hint: an example of this type was given in the introduction to this project.)
