The vapor pressure of water at 40.0 °C is Py = 7.34 x 10° Pa and the molecular mass of water is M = 18.0 g/mol. Enter your answer in units of grams per cubic meter. density: g/m3In order to increase the fuel efficiency and reduce structural failure of airplanes, new composite materials have been designed to replace airplane fuselages made of aluminum. Composite materials are low in density and tolerant to damage. One drawback of this new material is that it is not conductive. This increases the chance that a lightning strike will damage the plane. Engineers have redesigned the composites by adding a material to the original composition that is conductive. Identify one anticipated effect of this new material. Explain why the addition of the new material to the composite fuselage design will result in a tradeoff
