    Finding Electric Field at a Specific Point and on the Y-Axis

    Let a point charge Q1- 25 nc be located at (4,-2,7) and Q2= 60nc be at (-3,4,-2). a)Find E at (1,2,3) b)at what point on the y-axis is Ex=0 For part a) i found the electric field to be 68.92x-32.319y+85.936z b)would electric field on Ex be 0 at y=32.319??

    Chemical Reactions: Why we Use Symbols with Numbers

    I was wondering how come when ever there's a question like aluminum reacts with bromine it is usually written like Al + Br2? or Potassium reacts with oxygen is K + O2? How do we know when there's 2 of them?? Is there like a special rule? Why isn't there K2 or Al2??

    How can orthogonal trajectories be found for a specific family of curves?

    The set of orthogonal trajectories for the family indicated by ( x-c)^2 + y^2 = c^2 My work: y' = -(x-c)/y Since c= ( x^2 + y^2 ) / 2x plugging back in and doing -1/y' i got y' = 2xy / ( x^2 - y^2) Then I am supposed to move the x and y to a side and integrate but i don't...

    General Solution for Differential Equation: 6x y^2 -6x + 3 y^2 -3

    actually I am still having trouble do i still use the bernoulli method? so it is a simple separation problem?

    General Solution for Differential Equation: 6x y^2 -6x + 3 y^2 -3

    Give the general solution of: dy/dx = 6x y^2 -6x + 3 y^2 -3. No clue how to start. Guessing you would use Bernoulli's equation but i don't see how it is possible to put in the y'(x) + p(x)y(x) = q(x) y(x)^n form.

    What is the general solution for a differential equation involving e^x and e^-y?

    the general solution for ye^x dy/dx = [e^-y ] + [ e^ -2x-y ]is: so i tried to see if this was a homogenous equation but it is not. next i tried to simplify and got: y e^y dy= (1+e^-2x) dx / e^x

    How Long Would It Take for Earth to Reach 100°C?

    Homework Statement The Earth intercepts 1.27 ´ 1017 W of radiant energy from the Sun. Suppose the Earth, of volume 1.08 ´ 1021 m3, was composed of water. How long would it take for the Earth at 0°C to reach 100°C, if none of the energy was radiated or reflected back out into space? no...

    Is Temperature Constant in a Pressure-Volume Graph?

    Just wondering on a pressure volume graph is the temperature constant?? so does that mean the the heat taken in during the process is the negative of the change in energy of the gas??

    Does a constant volume and pressure change result in zero work done by a gas?

    if a gas in a container has a constant volume with a pressure change. Then the work done by the gas is 0 since there's not change in volume??
