In a feedback control scheme, gv = gm = 1, gp = exp(-0,25s)/(s+1), gd = exp(-0,25s)/(td*s+1) and exp(-teta*s) = 1 - teta*s, obtain gc(s) through direct synthesis method knowing that the regulatory answer is c/l = kd*s*exp(-teta*s)/(tc*s+1)^2, expressing the pid controller parameters in function of those in gp, gd and c/l.

2pos suppose an object in free fall is dropped from a building. its starting velocity is 0 m/s. ignoring the effects of air resistance, what is the speed (in m/s) of the object after falling 3 seconds? give your answer as a positive decimal without units. answer here

Effect of rotenone and antimycin a on electron transfer rotenone, a toxic natural product from plants, strongly inhibits nadh dehydrogenase of insect and fish mitochondria. antimycin a, a toxic antibiotic, strongly inhibits the oxidation of ubiquinol. (a) explain why rotenone ingestion is lethal to some insect and fish species. (b) explain why antimycin a is a poison. (c) given that rotenone and antimycin a are equally effective in blocking their respective sites in the electron-transfer chain, which would be a more potent poison? explain.
