Sound travels through different materials at different speeds. The speed of sound is defined by S=square root E over d Where S is the speed in meters per second, E is the elasticity of the material in newtons per square meter (N/meter square), and d is the density of the material in kilograms per cubic meter (kg/m cube). Determine the speed of sound through a material with E=750 N/m square and d =0.30 kg/m cube as a radical in simplest form
