#33.02\ "megawatts"#

#"P" = "Energy"/"Time"#

#color(white)("P") = ("nhc"/λ)/"t"#

#color(white)("P") = "nhc"/"λt"#

#color(white)("P") = (5.6 × 10^25 × 6.626 × 10^-34\ "J s" × 3 × 10^8\ "m/s")/(337.1 × 10^-9\ "m" × "1 s")#

#color(white)("P") = 33021892.6135\ "Watt"#

#color(white)("P") = 33.02\ "megawatts"#
