In an experiment, a varying force is applied tangentially for a period of time to a solid disk mounted on a frictionless axle. Initially, the disk is at rest. Which type of graph should be created so that the final kinetic energy of the disk is represented by the area under the graph?

Two identical small charged spheres are a certain distance apart, and each one initially experiences an electrostatic force of magnitude f due to the other. with time, charge gradually leaks off of both spheres. when each of the spheres has lost half its initial charge, the magnitude of the electrostatic force will be
