A20 kg object is acted on by a conservative force given by f = -3x - 5.x2, with f in newtons and x in meters. take the potential energy associated with the force to be zero when the object is at x = 0. (a) what is the potential energy of the system associated with the force when the object is at x = 6.0 m? (b) if the object has a velocity of 3 m/s in the negative direction of the x axis when it is at x = 8 m, what is its speed when it passes through the origin? what are the answers to (c) (a) and (d) (b) if the potential energy of the system is taken to be -6 j when the object is at x = 0?

How do the measurements of charge at the different locations on the sphere compare to each other? the charge measurements are different at all locations on the sphere. the charge measurements are virtually not the same at all locations on the sphere except for the charge at the very top and at the very bottom that are equal. the charge measurements are virtually the same at all locations on the sphere except for the charge at the very top. at the top, the conductive sphere has a small disk that is made of different material. the charge measurements are the same at all locations on the sphere. what happens to the charge on the conductive sphere when it is connected to a source of charge such as the electrostatic voltage source? nothing will happen because no charge goes around the surface of the sphere. the charge on the conductive sphere spreads out over the surface of the sphere; being greater in some specific locations on the sphere. the charge on the conductive sphere spreads out uniformly over the surface of the sphere. the charge on the conductive sphere spreads out non-uniformly over the surface of the sphere.
