... 13. (c) The rms speed of a gas is an average molecular speed found by taking the square root of the average of the square of the molecule speeds. Consider a gas in which 2/3 of the molecules are at rest and 1/3 ... 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

... 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

... 13. (d) Students frequently confuse the medium (an object) with the wave motion and answer that the waves will collide and bounce off of each other. The waves obey the superposition principle such that at any ... See full document

... 13. Eddy current brakes will work on metallic wheels, such as copper and aluminum. Eddy current brakes do not need to act on ferromagnetic wheels. The external magnetic field of the eddy brake just needs to ... See full document

... 13. One reason you can see a drop of transparent and colorless water on a surface is refraction. The light leaving the tabletop and going through the drop on the way to your eye will make that portion of the ... 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

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

... Using the right-hand rule, we see that if the currents flow in the same direction, then the magnetic fields will oppose each other between the wires and therefore can equal zero at a gi[r] ... See full document

... 13. Chromatic aberrations in lenses occur due to dispersion, which is when different colors (or wavelengths) of light are bent different amounts due to the fact that the index of refraction of most materials ... 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

... 13. Active noise reduction devices work on the principle of destructive interference. If the electronics are fast enough to detect the noise, invert it, and create the opposite wave (180° out of phase with 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 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

... 13. The two extra electrons held by the newly formed thorium will be very loosely held, as the number of protons in the nucleus will have been reduced from 92 to 90, reducing the nuclear charge. It will be easy ... 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

... 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

... 13. (c) In a two-prong cord, one prong is at high voltage and the other is grounded. Electricity flows through the appliance between these two wires. However, if there is a short between the high- voltage wire ... 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
