    Engineering Is it possible to solve for VL in this parallel RL circuit?

    Homework Statement I have the following parallel RC circuit. At time T = 0, the switch will close and the circuit will be connected. We assume that prior to T = 0, the circuit was at a steady-state. I want to calculate VL(t) -- but I am being told that this is not possible for this...

    Water + Water Vapor - Can I use ideal gas law?

    Is it possible for the ideal gas law to be used in any way for this problem? I am simply surprised, because the core of the chapter which contains this problem discusses the ideal gas law and the book's tables provide Cp and Cv for both saturated water/steam in both liquid and vapor forms. My...

    Water + Water Vapor - Can I use ideal gas law?

    The problem note that the water remains in a saturated state. I would assume this indicates it does not become a gas, is this correct?

    Water + Water Vapor - Can I use ideal gas law?

    Homework Statement Sealed container which is used to heat 200 kg water is initially at 25 degrees C. Since the container is sealed, the water remains in saturated state while its temperature and pressure increases. The remaining volume of the container is filled with water vapor at the same...

    Converting between Sums of Products & Products of Sums

    So why is such a "complex" method required to convert from sums of products to products of sums? Why do I need to utilize DeMorgan's theorem for this conversion?

    Practical limit on Resolution (Diffraction Grating)

    Homework Statement In order to increase resolution of the diffraction gratings we can use them in higher orders of diffraction. What is the practical limit on using very high orders of diffraction? Homework Equations R = \lambda / \Delta\lambda = Nm The Attempt at a Solution I...

    Basis for Vector Space: Understanding the Exceptional Case

    Homework Statement My notes has the following statement, but I seem to have forgotten to write down the conclusion of the statement before my professor erased it from the board. "Any vector space V there will be a basis except for 1 type of space: " Any ideas as to what that 1 type of...

    What is the total force exerted by two charges on a point charge at the origin?

    My apologizes if the "attempt at a solution" section appeared blank for anyone -- I have changed the link so that users who are not logged in can now see the link.

    What is the total force exerted by two charges on a point charge at the origin?

    Homework Statement Two point charges are placed on the x-axis as follows: one positive charge, q1, is located to the right of the origin at x= x1, and a second positive charge, q2, is located to the left of the origin at x= x2. What is the total force (magnitude and direction) exerted by...

    What do the sample points mean in a double integral problem?

    Homework Statement I am getting rather confused when I attempt to solve one of these double integral problems. A typical problem is phrased like this: If R = [-1, 3][3,5], use a Riemann sum with m = 4, n = 2 to estimate the value of the following \int\int(y^{2}-2x^{2} The problem will...

    Rotational Inertia of merry go round

    Homework Statement a. A merry go round is rotating in the counter-clockwise direction. Initially, a 50 kg child is sitting on the edge of the merry-go-around, which rotates at 0.5 radians per second. The moment of inertia of the merry-go-round is 2150 kg-m2. The radius is 2.50 meters. The...

    The page title could be Projectile Motion Problem: Calculating Work and Velocity

    Homework Statement There are four different components to this problem. Each component is short -- so don't worry. a. Suppose you throw a 0.4 kg ball straight upwards from a height of 1.5 m, at a speed of 4.0 m/sec. How much work have you done on the ball by accelerating it from rest to 4.0...

    Finding Pairs of Integers with GCD 14 and LCM 168 | Discrete Math Homework

    thanks, i have no trouble with prime factorization, it's just that lcm and gcd are a little iffy with me... i was hoping for a quicker solution since i don't want to take so long on one problem on test not to mention a final
