molecules of solute move down their concentration gradient with the aid of membrane protein requires energy for transport movement of a solvent down the solvent gradient uses a concentration gradient of one molecule to move another molecule against its concentration gradient
Question 5 (1 point) Listen Given A bar having a length $L_0$ of 4.85 in. and cross-sectional area of 0.85 in$^2$ is subjected to an axial force of 7700 lb. P $L_0$ P Required If the bar stretches 0.002 in., determine the modulus of elasticity for the material in $10^3$ ksi to the nearest 10th, i.e., one (1) decimal place. Assume it remains linear elastic.

A 30 full-wave diode rectifier consists of 6 separate semiconductors within a single package. The junction to case thermal resistance of each diode is 0.12° C/W. The diode rectifier is mounted on a single heatsink with a case to heatsink thermal contact resistance of 0.1° C/W and a heatsink to ambient thermal resistance of 0.1 °C/W. Under the maximum rated load conditions the rectifier output current is ripple-free at 120 A. The diode on-state junction voltage is 0.9 V and you may neglect the diode on-state resistance. The ambient temperature is 35° C. (a) Determine the junction temperature of a diode. (b) If one diode has a poor connection to the case and its junction to case thermal resistance is 0.5° C/W, determine its temperature and that of the other 5 diodes.
