Agaussian pulse of voltage v(t), described by v(t) = ae-a(t-to)2 is applied to the terminals of a very small parallel-plate capacitor with plate area s (each plate) and plate separation d. within the frequency range of the pulse, the dielectric inside the capacitor can be characterized by a frequency-dependent permittivity e-e-je"', where ω-2, and f is the operation frequency. the conductivity of the dielectric is oe neglecting fringe effects, determine an expression for the current i(t) fow- ing in the capacitor terminals.

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
