Question

GILA How much energy is given to the cell during this pulse? Express your answer in joules to two significant figures. 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 4.8 pm in diameter, with the pulse lasting for 3.0 ns with an average power of 1.71x1012 W. We shall assume that the energy is spread uniformly over the faces of 100 cells for each pulse. Submit Request Answer Part B What is the intensity (in W/m²) delivered to the cell? Express your answer to two significant figures. IVO AMO ?
