Please do all parts if possible, I dont need explanation just answer, Thank you:   TRUE OR FALSE:  a) Glasses are usually harder than plastics but softer than silicon carbide and boron carbide b)  Any amorphous (lacking in long-range periodic order) materials, inorganic, organic, or metallic, formed by any techniques, exhibits glass transformation formation behavior are glasses  c) In general, the viscosity is low at the melting position of glass, and high at room temperature. d) In general, if the viscosity is very high at the melting position of the corresponding crystalline phase which would form the melt, it is much easier to form glass for this melt. e) The glass fiber is possible to have a tensile strength even larger than that for iron or structural steel. Therefore, in the practical applications, we should be able to use glasses for the same purposes of the iron or structural steel.

In a continuous fibre reinforced composite where the fibres are well aligned, the strength in the transverse direction will be the strength in the longitudinal direction. The stiffness of the composite in the transverse direction will be the stiffness in the longitudinal direction. greater than similar to less than
