Do the following and plot all the waveforms. a boost converter is required to have an output voltage of 12 v and supply a load current of 1.5 a. the input voltage varies from 2.7 , 4.2·ev a control circuit adjusts the duty ratio to keep the output voltage constant. select the switching frequency. determine a value for the inductor such that the variation in inductor current is no more than 30 percent of the average inductor current for all operating conditions. determine a value of an ideal capacitor such that the output voltage ripple is no more than 1 percent. determine the maximum capacitor equivalent series resistance for a 1 percent ripple. f-500khz

Two red blood cells each have a mass of 9.0 multiply.gif 10-14 kg and carry a negative charge spread uniformly over their surfaces. the repulsion arising from the excess charge prevents the cells from clumping together. one cell carries −2.50 pc of charge and the other −3.10 pc, and each cell can be modeled as a sphere 7.5 μm in diameter. (a) what speed would they need when very far away from each other to get close enough to just touch? assume that there is no viscous drag from any of the surrounding liquid. answer is: 321 m/s how do i find this (b) what is the maximum acceleration of the cells in part (a)? answer is: 1.38e+10 m/s2 how did they find this answer
