    What Does Extensity Mean in Endoreversible Thermodynamics?

    I am doing a project for my thermodynamics class and I have decided to do it on Endoreversible Thermodynamics. I Have read a few articles but I am having some difficulty understanding parts of it. I have not read the whole article, still in the beginning. But from the intro are they saying that...

    Derive the fundamental equation from and equation of state

    Hello, I just need help deriving the fundamental equation from Equation of state for wan der waals fluids. P=\frac{RT}{v-b}-\frac{a}{v^2} and u=cRT-\frac{a}{v} where a,b, and c are constants. I know the fundamental equation is dS=\frac{1}{T}dU+\frac{P}{T}dvI solved the u equation so it's...

    Three species reversible reaction rate

    The problem statement says to derive the concentration as a function of time for the general three species first order reactions. I have attached an image of the problem, so see the image for the reaction. I have written the reaction rates for all the reactions but I am having trouble...

    Finding Michaelis-menten constant and Vmax

    Ok, here is the problem A single-substrate enzyme catalyzed reaction was investigated in the presence of 1.0 mM inhibitor as well as in the absence of inhibitor, the intial substrate concentration being constant throughout. The following results were obtained: ----------------intial velocity...

    How Is the Maximum Swing Angle Determined in an Elastic Collision?

    yeah, and i got an answer that did not seem right. I used the equation to find the final velocity of the block after it was hit by the ball. The velocity of the ball will -5m/s right after it hits the block because this is an elastic collision, or is that wrong. But any ways use the kenitic...

    How Is the Maximum Swing Angle Determined in an Elastic Collision?

    yeah i forgot its elastic, so the ball bounces back off. But how will i go about finding the angle.

    How Is the Maximum Swing Angle Determined in an Elastic Collision?

    Ok here is the problem A ball with mass M moving horizontally at 5.00 m/s, collides elastically with a block with mass 3M that is initially hanging at rest from the ceiling on the end of a 50.0-cm wire. Find the maximum angle through which the block swings after it is hit. Ok what i...

    How Do You Calculate Spring Constant for Launching a Satellite?

    You are asked to design a spring that will give a 1160 kg satellite a speed of 2.85 m/s relative to an orbiting space shuttle. Your spring is to give the satellite a maximum acceleration of 5.00g. The spring's mass, the recoil kinetic energy of the shuttle, and changes in gravitational potential...

    Help with projetile motion using Energy Theorem

    I just wanted some one to check over my answer because i am doing my homework online and it keeps telling that my answer is close, and that i have made a rounding error or used the wrong sig figs. The problem is A baseball is thrown from the roof of a building of height 22.1 m with an...
