Multiple-Object Accelerating Systems: Two objects of unequal masses, M and m (M > m), are connected by a very light cord passing over an ideal pulley of negligible mass. When released, the system accelerates, and friction is negligible. 
Which one of the following free-body diagrams most realistically represents the forces acting on the two objects in the moving system?
A. 
B. 
C. 
D.

Is there any method by which we can detect individual atoms in the laboratory?
A) Yes, by using microscopes based on X-rays rather than on light. B) Yes, by using very high power microscopes based on visible light of very short wavelength. C) No, because atoms are purely mathematical abstractions and not real physical objects. D) Yes, by using microscopes based on the "matter waves" made by material particles such as electrons. E) No, because atoms are smaller than any physical wavelengths.
