a powerful laser pulse cannon fires that is firing lasers. each laser pulse lasts 6.66 micro seconds. the electric field of the laser has a value E(rms) 7.75*10^8 N/C, if the circular-section of the beam is set to 0.120 cm.
1) what is the average intensity of the laser
2) what is the average power of each pulse
3) how much energy is contained in each pulse.
4) what is te value B(rms) for the beam.
