using a plane wave model, estimate the following quantities
a)the magnitude of the electric and magnetic fields in a 5 mw hene (\lambdao=633 nm) laser beam in air. assume the power is ~evenly distributed in a beam of diameter ~0.5 mm. b) the intensity (irradiance is becoming the more accepted term, actually) of a co2 (\lambdao=10.6 \mum) laser beam at a focal point that is causing air breakdown. use the low frequency breakdown strength of air, ~3 x 106 v/m.
c) the electric field magnitude in a nd-glass laser beam, with \lambdao=1.06 \mum, which is producing 5.2 kj pulses with a duration of 0.8 ns. assume the beam is focused to a spot with diameter of 0.2 mm (in air).

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
