... 12. The speed of the transverse wave is the speed at which the wave disturbance moves along the cord. For a uniform cord, that speed is constant and depends on the tension in the cord and the mass density of the cord. ... See full document

... the solutions manual, relative to the 2002 class, which did not have access to the solutions ...the instructor, since the two classes were as similar in these aspects as likely to be ... See full document

... Since the increasing clockwise current in the front loop is causing an increase in the number of magnetic field lines down through the second loop, Lenz’s law states that the second lo[r] ... See full document

... The statement to justify is this: “Equivalently, the image distance is positive for a real image and negative for a virtual image.” The three cases to consider are for a diverging lens,[r] ... See full document

... 11. (e) If the film has regions of lower index of refraction on both sides of the film (or higher on both sides), then a phase shift will occur at one surface but not the other. In this case constructive ... See full document

... The mass of the wire is the density of copper times the volume of the wire, and the resistance of the wire is given by Eq... The resistance can be calculated from the power and voltage,[r] ... See full document

... When two small nuclei are fused together, the total energy of the resulting nucleus is smaller than the energy of the two initial nuclei, with the excess energy released in the fusion p[r] ... See full document

... lens, is typically used by adjusting the distance between the lens and the object so that the object is exactly at or just inside the focal point. An object exactly at the focal point results in an image that is at ... See full document

... 11. No, fewer electrons are emitted, but each one is emitted with higher kinetic energy, when the 400-nm light strikes the metal surface. The intensity (energy per unit time) of both light beams is the same, but ... See full document

... 11. The wave pattern created by standing waves does not “travel” from one place to another. The node locations are fixed in space. Any one point in the medium has the same amplitude at all times. Thus, the ... See full document

... 10. Any imbalance of charge that exists would quickly be resolved. Suppose the positive plate, connected to the positive terminal of the battery, had more charge than the negative plate. Then negative charges from the ... See full document

... 11. (c) A common misconception is that the digital broadcast uses a different frequency than the analog broadcast. This is incorrect—the carrier wave frequency is the same. Since the antenna is designed for ... See full document

... (b) The magnetic dipole moment is defined in Eq. 20–11 as M = NIA . The number of turns, N, is 1. The current is the charge per unit time passing a given point, which on the average is the charge on the electron ... See full document

... 23. The decay series of Fig. 30–11 begins with a nucleus that has many more neutrons than protons and lies far above the line of stability in Fig. 30–2. The alpha decays remove both 2 protons and 2 neutrons, but ... See full document

... The Bohr model does violate the uncertainty principle, specifically by saying that an electron in a given orbit has a precise radius and a precise momentum.. The uncertainty principle s[r] ... See full document

... 10. (b) Both the monkey and bullet fall at the same rate due to gravity. If the gun was pointed directly at the monkey and gravity did not act upon either the monkey or bullet, the bullet would hit the monkey. Since ... See full document

... The electric field is strongest to the right of the positive charge (on the line connecting the two charges), because the individual fields from the positive charge and negative charge [r] ... See full document

... When resistors are connected in parallel, the current from the battery or other source divides into the different branches so the equivalent resistance is less than any individual resis[r] ... See full document

... 10. If there were no air resistance, the ball’s only acceleration during flight would be the acceleration due to gravity, so the ball would land in the catcher’s mitt with the same speed it had when it left the bat, 120 ... See full document

... (d) The car is exerting a 400-N horizontal force on you, and since you are not accelerating, and the only horizontal forces acting on you are the force from the car and the frictional [r] ... See full document
