... 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 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

... 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

... 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 ... See full document

... 12. (d) If the charger unit had a battery, then it could run the laptop without being plugged in. A motor converts electrical energy into mechanical energy, but the laptop charger output is electrical energy, not ... 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 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

... 12. The right-hand rule tells us that as the positive particle moves to the right, if it is deflected upward, then the magnetic field must be into the page, and if it is deflected downward, then the magnetic ... 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

... 80. The potential difference gives the electrons a kinetic energy of 12.3 eV, so it is possible to provide this much energy to the hydrogen atom through collisions. From the ground state, the maximum energy of the atom ... See full document

... 12. A force is required to increase the separation of the plates of an isolated capacitor because you are pulling a positive plate away from a negative plate. Since unlike charges attract, it takes a force to ... 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

... 12. For the gravitational force, we don’t notice it because the force is very weak, due to the very small value of G, the gravitational constant, and the relatively small value of ordinary masses. For the ... See full document

... 12. (a, b) Radiation is composed of high-energy particles that can disrupt cells. If a small amount of radiation hits the correct molecules of a cell (such as DNA), then it can alter the cell, causing cancer. ... 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

... 11. The two spheres have different rotational inertias. The sphere that is hollow will have a larger rotational inertia than the solid sphere. If the two spheres are allowed to roll down an incline without slipping, the ... 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

... 12. When batteries are connected in series, their emfs add together, producing a larger potential. For instance, if there are two 1.5-V batteries in series in a flashlight, then the potential across the bulb will ... 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
