Lasers can be constructed that produce an extremely high intensity electromagnetic wave for a brief time—called pulsed lasers. they are used to ignite nuclear fusion, for example. such a laser may produce an electromagnetic wave with a maximum electric field strength of 1.52\times 10^{11}~\text{v/m}1.52×10 11 v/m for a time of 1.00 ns. what energy does it deliver on a 1.00~\mathrm{mm^2}1.00 mm 2 area?

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
