Congress forcing a compromise(d) Space Shuttle design on NASA. Among other things, the space shuttle was the first human space vehicle to use solid rocket boosters. Solid rocket boosters were previously deemed unsafe for human space flight because once they're lit, they don't stop boosting until the fuel is gone. Liquid-fueled rockets can be shut off.
Definition of conductive. : having conductivity : relating to conduction (as of electricity)
Electrical conductivity is also known as specific conductance. Conductivity is an intrinsic property of a material. Units of Electrical Conductivity. Electrical conductivity is denoted by the symbol Ï and has SI units of siemens per meter (S/m). In electrical engineering, the Greek letter Îº is used. Sometimes the Greek letter Î³ represents conductivity. In water, conductivity is often reported as specific conductance, which is a measure compared to that of pure water at 25Â°C. Relationship Between Conductivity and Resistivity. Electrical conductivity (Ï) is the reciprocal of the electrical resistivity (Ï): Ï = 1/Ï
