... independent of the path followed. In the graph shown, the work done in going from point A to B to C by the isobaric and isovolumetric processes is equal to the area under the AB line.[r] ... See full document

... 15. (d) The gravitational force between nucleons is much weaker (about 50 orders of magnitude weaker) than the repulsive Coulomb force; therefore, gravity cannot hold the nucleus together. Neutrons are ... 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

... 1. For an underdamped oscillation, the period is approximately equal to the period of an undamped oscillation. The period is related to the mass and spring constant as in Eq. To measure[r] ... See full document

... 15. The nonferrous materials are not magnetic, but they are conducting. As they pass by the permanent magnets, eddy currents will be induced in them. The eddy currents provide a “braking” mechanism which will ... 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

... The phase difference caused by the path difference back and forth through the coating must correspond to half a wavelength in order to produce destructive interference.. We first find t[r] ... See full document

... The 15-A fuse is blowing because the circuit is carrying more than 15 A of ...carry 15 A, so there might be a “short” or some other malfunction causing the current to exceed 15 ...the ... See full document

... 15. No, you cannot set a resting electron into motion with a magnetic field (no matter how big the field is). A magnetic field can only put a force on a moving charge. Thus, with no force (which means no ... See full document

... 15. Spherical aberrations can be present in a simple lens. To correct this in a simple lens, usually many lenses are used together in combination to minimize the bending at each of the surfaces. Your eye ... See full document

... ( a ) At the threshold wavelength, the kinetic energy of the photoelectrons is zero, so the work function is equal to the energy of the photon.. 27–5b to calculate the maximum kinetic [r] ... See full document

... Doppler effect. We analyze the case of the wind blowing from the source toward the listener. The moving air (wind) has the same effect as if the speed of sound had been increased by an amount equal to the wind speed. The ... See full document

... ( b ) After the first capacitor is disconnected from the battery, the total charge must remain constant, and the voltage across each capacitor must be the same, since each capacitor pl[r] ... 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

... The power output of the antenna would be the intensity at a given distance from the antenna times the area of a sphere surrounding the antenna.. The intensity is given by Eq.[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

... Since friction is the only other force acting on the coaster, the work done by friction can be calculated as the change in mechanical energy between the initial and final positions. ( b[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

... 82. As shown in Example 2–15, the speed with which the ball was thrown upward is the same as its speed on returning to the ground. From the symmetry of the two motions (both motions have speed = 0 at top, have ... 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
