    How Do You Determine Pipeline Pressure with a Faulty Manometer?

    Homework Statement You are given an open-ended mercury manometer and asked to determine the pressure in a pipeline that supplies feed gas to a reactor. However, when you connect the manometer to the pipeline, you notice that the calibration markings in the leg that connects to the...

    Undergrad Conceptual Circuits: Understanding Electric Fields

    I'm just trying to get a conceptual grounding for the circuit problems in our book. So I understand that a circuit maintains a potential difference via redox reactions. The electrons have a desire to flow, so they do so. The potential difference and the conducting wire allow the...

    Angular Momentum for Man and Bullet

    Homework Statement A man, mass M, stands on a massless rod which is free to rotate about its center in the horizontal plane. The man has a gun (massless) with one bullet, mass m. He shoots the bullet with velocity Vb, horizontally. Find the angular velocity of the man as a function of the angle...

    Correctness of my equation relative to the standard given in the text

    That looks absolutely terrible in terms of written form, but alright. I thought R(x) had to be a function containing x. I see now. Thanks. Oh and sorry i meant long division, I posted that around 1 last night. Haha

    Correctness of my equation relative to the standard given in the text

    Homework Statement Given a polynomial P(x) and a divisor D(x), divide P(x) by D(x) and return the answer in the form P(x)/D(x) = Q(x) + R(x)/D(x) In this case: P(x) = 4x^2 - 3x - 7 D(x) = 2x -1 Homework Equations The one given above The Attempt at a Solution I solved the...

    Solving a 2.2kg Block Incline Problem

    Homework Statement A 2.2kg block slides down a planar incline. The incline makes an angle of thirty degrees with the horizontal and the block starts 10 m above ground. The coefficient of friction between the block and the incline is .1. The block reaches the bottom of the incline and then...

    Force at Equilibrium: How to Solve X and Y Components of Tension

    I think I got it now, just one question. Are you supposed to add the vertical components of both of the systems in order to get the weight of Fw1?

    Force at Equilibrium: How to Solve X and Y Components of Tension

    Homework Statement I have an actual image which is quite better than my poor descriptive skills Homework Equations The X and Y components of each tension must balance.The Attempt at a Solution I thought if F3 weighs 200N then that mean the X component of Fw1 must equal Fw1 tan(35)=200...
