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=

The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ft⋅lbflbm⋅r(1 psia144 lbf/ft2) = 0.3704 psia⋅ft3lbm⋅r the amount of air that must be added to raise the pressure is lbm
