    Gen Chem II Voltaic Cells question, not homework

    Im try to make sure i understand something right. I have two jars on the left is oxidation takes place and on right reduction takes place. A wire connects them to allow electrons to move. electrons move from left side to right side. This makes the left side negative cause it produces electrons...

    Understanding Thermodynamics: Demystifying the Chain Rule for Integration

    I am reading a thermodynamics book. I am confused on how they say use the chain rule Here. it makes no sense to me how they go from dV/dt to (dV/ds)(ds/dt) . I know how the chain rule works ,just don't know where they got these values

    Projectile motion y=f(x) type ,

    Yes. I got that but how do i solve for the dy/dt and dx/dt that's what i don't get .

    Projectile motion y=f(x) type ,

    This is for my dynamics class, but anywaya. A particle moves along a curve y=e2x such that its velocity has a constant magnitude of v=4ft/s. Determine the x and y components of the velocity when y =5ft ? Im confused on this. So when i plug 5 into the equation is get .804 ft. Now that's the...

    Find Fourier Series of f(t)=2u(t)-2u(t-2) with T=4s | Step Function Question

    consider f(t)=2u(t)-2u(t-2) Volts between t=0 and t=4 seconds. So i have to find the Fourier Series Representation of this given that T=4 secounds. I am not worried about the Fourier part. If i draw the f(t) function out on graph its 2 Volts from t=0 till t=2 seconds and then wehn it gets to 2...

    How Do You Determine the Direction of a Moment in Statics?

    Homework Statement How do i know how to calculate it properly ? Like i Know M=Fd but, how can i tell if its positve counterclockwise or negative clockwise. Expecially when you have components. Something Like this that's broken into compoents how can i calculate the moment ? I am totally...

    Phasors and Imaginary and Real help

    Ok so i just want to clear up something about phasors and just circuit input functions in general. So based on the imaginary and real graph, where imaginary is like the y-axis and the real is the x axis, when let's say a circuit falls on the imaginary axis is it considered a stable circuit? Do...

    How can i tell a period of a function involving sin and cos

    Homework Statement Ok so we started Fourier Analysis in circuits. How can i tell the Period of a function that's let's say sin(2t)+3cos(5t) something like that . Any help or url's that have information on this

    Doughnut-shaped Universe: Astronomers say Universe is small and finite

    That is very interesting , but i have read that the universe is flat. They carried out some experiment where they launched two beams from Earth and always addded up to 180 degrees a right trangle. Earth is the location of 90 degrees on a triangle

    Does the Universe Operate on Mathematical Logic?

    Does the universe follow a mathematical logic? It seems to me it does. yes we don't know everything about the universe but as we have learned more it still holds up to be logical.

    What is the Difference between Electrical Engineering and Electrical techonology

    What is the is the difference between those two? I know what electrical engineers do , but what about electrical technology. Can someone list some key differences, and how much different is the salarys between these two.

    Engineering Short Circuit, and open circuit question

    Homework Statement What is the difference between an open circuit and a short circuit? Open circuit has no current, so does that mean any resistor in series with it, has no current ,so it can be ignored for analysis( v=ir so 0 current means 0 V) for finding let's say the Thevenin...
