... 6. The slit spacing and the distance from the slits to the screen are the same in both cases. The distance between bright fringes can be taken as the position of the first bright fringe (m = 1) relative to the central ... See full document

... 24. It is possible for the de Broglie wavelength ( λ = h p / ) of a particle to be bigger than the dimension of the particle. If the particle has a very small mass and a slow speed (like a low-energy electron or ... See full document

... Use the average atomic weight as the average number of nucleons for the two stable isotopes of copper to find the total binding energy for one copper atom.. = ≈ 550 MeV.[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

... ( 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

... We combine the expression for the frequency in a closed tube with the Doppler shift for a source moving away from a stationary observer, Eq... As the train approaches, the observed freq[r] ... 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

... For a distant object and a relaxed eye (which means the image is at infinity), the separation of the eyepiece and objective lenses is the sum of their focal lengths.. 25–3 to find the m[r] ... See full document

... 24. The magnetic domains in the unmagnetized piece of iron are initially pointing in random directions, as in Fig. 20–42a (which is why it appears to be unmagnetized). When the south pole of a strong external ... 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

... 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

... 31. There are (24 h)(60 min/h)(60 s/min) 86, 400 s = in a day. The clock should make one cycle in exactly two seconds (a “tick” and a “tock”), so the clock should make 43,200 cycles per day. After one day, the ... 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

... 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

... 24. Spontaneous emission occurs when an electron is in an excited state of an atom and it spontaneously (with no external stimulus) drops back down to a lower energy level. To do this, it emits a photon to carry ... See full document

... When using conservation of energy to relate the total initial kinetic energy (translational and rotational) to the final potential energy, the mass and radius of the objects cancel out[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

... 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

... If north is defined as the positive direction, then an object traveling to the south and increasing in speed has both a negative velocity and a negative acceleration.. Or if up is defin[r] ... See full document
