Consider the circuit below: (a)calculate the voltage vout as a function of the resistance r0. (b)suppose the resistance r0 has an initial value of 16ω, and that r0 is then changed to a value of 32ω. what is the change in power supplied by each of the independent sources in the circuit when r0 is changed from 16 ω to 32 ω? (c)use superposition to determine the contribution of each independent source to the current flowing across the 2ω resistor located between the 4a and 12v sources (in the direction indicated by the arrow).

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.
