    Solving for "a" in Square Root Equation

    It gives me this: 12+\sqrt{36-a}=14 could I be going wrong somewhere?

    Calculating Work: Gas in a Horizontal Cylinder Heated from 300K to 400K

    I think that the PV graph in this case should be a straight line parallel to the x-axis since the pressure is constant but the volume is varying(since the piston is moving). I am not sure about this but since the pressure is constant I think this is an isobaric process and the work done can be...

    Is the charge induced on a conductor equal to or less than the inducing charge?

    I think they are equal since every single charge induces an opposite charge on the conductor. The opposite charges on the conductor that correspond to those on the inducing material are assumed to be all earthed.

    Calculating Work: Gas in a Horizontal Cylinder Heated from 300K to 400K

    I have edited the question. It is not stated that the gas is monoatomic and that is one of the things that make me think that my method is wrong. My argument is the energy gained by the gas is equal to the difference in internal energy of the gas before heating and after heating.

    Calculating Work: Gas in a Horizontal Cylinder Heated from 300K to 400K

    Homework Statement A cylinder with a frictionless piston is placed horizontaly in an atmosphere of pressure 1.0×10^5N/m^2.A gas in the cylinder is initially at a temperature of 300K with a volume of 1.0 ×10^-3 m3.Then , the ags is heated slowly to a final temparature of 400k.How much work is...

    Solve for a When Parabola y=x^2-a(x+1)+3 Intersects x-Axis Once

    I redid it. I got this: y+(1/4)a^2+a-3=(x-(1/2)a)^2 and solved a to be -6 or 2

    Solve for a When Parabola y=x^2-a(x+1)+3 Intersects x-Axis Once

    Oh my mistake, I got this y+(1/4)a^2-3=(x-(1/2)a)^2 Is that what you have?

    Solve for a When Parabola y=x^2-a(x+1)+3 Intersects x-Axis Once

    I get something to this effect; y+1/2a-3=(x-1/2a)^2 I get stuck because the y part cannot be factorized but I am again thinking that the I could equate 1/2a-3=0 because apparently the left side should not have a constant since the vertex is along the x-axis.That could give me one of the values...
