Homework Statement I'm doing an assignment on cathodic protection systems using solar energy and have no idea on how to construct an efficient system. All the ones online are too basic and don't specify whether the panels are in series or parallel or not. I've calculated that the system needs...

Glass or fiberwool would be the best but honestly, at this rate i would be fine with any value regardless of the type of wool. Also thanks for replying.

Homework Statement I need this to find the the reflective coefficient and multiply this by 100 to find the percentage of original energy reflected back however i cannot find the acoustic impedance of wool no matter how hard i try. Homework Equations Im using the reflective coefficient formula...

Homework Statement Someone throws a ball 1m from the ground at a 30 degree angle to the corner of the room 8m away and elevated by 1m. Find the initial velocity of the ball. Homework Equations s=ut+1/2at^2 The Attempt at a Solution So i broke it up into vector components in order to find the...

Homework Statement Okay so we're testing the effects different types and number of layers can have the heat released through conduction. in our results we found that the heat released was reduced by 50% for 2 layers compared to 1 layer and that the heat released was reduced to 34% for 3 layers...
