    How Does Distance Affect Electric Flux Through a Square?

    Well since Flux = E dot dA, you need to find the Electric field going through the side of the square. So the distance from the square is r in the equation for an electric field due to a point charge ( E = kq/(r^2) ).

    What Forces Affect the Acceleration of an Airboat?

    use DeltaX = volt + 1/2 at^2 remember he is starting from rest (Vo = 0, so the term drops) solve for a(acceleration) then multiply acceleration by the mass to get the net force from Newton's Second Law.

    You can NOT solve this Problem, however please give it a try

    Is weight added, or is mass added. The addition of weight implies that the object is now under a gravitational force. If "weight" is added, the path will change, because the object will undergo an acceleration. However, if only MASS is added, and the object is not under the force of gravity...

    How Thick Would an Infinite Plate Need to Be to Mimic Earth's Gravity?

    Okay, so I figured it out and no longer need help. What I did was find the integral(g dot dA) of the spherical earth, which was 4piGm, and set that equal to the integral(g dot dA) of the infinite plate earth. Evaluating the integral, and doing some tricky substitutions with p = m/v, I found...

    How Thick Would an Infinite Plate Need to Be to Mimic Earth's Gravity?

    Homework Statement Imagine the Earth is indeed not a sphere of radius r, but an infinite plate of thickness H. What value of H is needed to allow the same gravitational acceleration to be experiences as on the surface of the actual Earth? (Assume the Earth's density is uniform and equal in...
