    How can I use the Excel solver to solve systems of equations?

    Graphing always works when in doubt just graph them and see what kind of a soluiton set you get. Remeber greater then shades up and less than shades down.

    How Do You Calculate Tension and Compressive Forces in Engineering?

    These Forces are in equilibrium and aren't moving so when you setup your (Sum)F = ma in the x and y direction the right side of the equation will go to 0. Leaving you with (Sum)Fx = 0 and (Sum)Fy = 0. From there I'm not to sure with a tensile factor what equation to use but I'm guessing that...

    How Does Heat Transfer Affect Entropy Between the Sun and Earth?

    The forumula that you would want to use is Gibb's Free Energy Equation. deltaG = Heat of Formation - (TdeltaS) then with a little calculus you can reach the forumula S = e^-deltaG/RT and don't forget to change to the correct units.

    Solving a Physics Problem: Inverted Image & Lens Separation

    I have this Physics Problem which I am not to sure where to start it from. The problem is: A real inverted image I of an object O is formed by a certain lens. The object-image speration is d = 0.40m, measured along the central axis of the lens. The image is just half the size of the...

    Power of Consecutive Fans: Double the Speed?

    The fan speed will not increase by putting one behind another, but by putting them next to each other will create a greater area covered and more of a "breeze" effect. Both Dave and quark were correct
