The dynamic behaviour of an industrial distillation column of ar to be reasonably characterised by the following transfer function distillation column of an unusual design is g(s) = 2-5-12 1 1 how many poles and how many zeros y poies and how many zeros does this system transfer function have and where are they located? (5) 1 2 determine the output response for a unit step change in input.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

since electrons are negative the answer is neagtaive
