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?
Express your answer to two significant figures.
