(a) What is the intensity in W/m² of a laser beam used to burn away cancerous tissue that, when 94.0% absorbed, puts 460 J of energy into a circular spot 2.90 mm in diameter in 4.00 s? |W/m² (b) Discuss how this intensity compares to the average intensity of sunlight (about 700 w/m2) and the implications it would have if the laser beam entered your eye. Note how your answer depends on the time duration of the exposure.
