26. Can an object be moving at a constant speed, but still have acceleration? A. Yes, because the object is gaining speed at a constant rate. B. Yes, because the object is changing direction. C. No, if it's moving at a constant speed it is not accelerating. D. No, because the object will eventually slow down. 27.In the quantum theory of hydrogen, as an electron drops to lower EPE orbit, it emits a photon with missing energy equal to A....
