1.I want to build a filter that eliminates the frequency 294Hz, assuming a sample rate of 44,100 samples per second. I don't care what this filter does to other frequencies, only that 294Hz is eliminated. Write a transfer equation for this filter.

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.

What is a monomer? how do they form a ploymer from the view point of chemical bonding?

Starting wih an energy balance on a rectangular volume element, derive the one- dimensional transient heat conduction equation for a plane wall with constant thermal conductivity and no heat generation.
