... 77. The coil should have a diameter about equal to the diameter of a standard flashlight D-cell so that it will be simple to hold and use. This would give the coil a radius of about 1.5 cm. As the magnet passes through ... 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

... 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 clock in ... 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

... 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

... 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

... ( 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

... 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

... ( 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

... Assume that the neutrino distribution is spherically symmetric, centered at the Sun. The fraction that would pass through the area of the ceiling can be found by a ratio of areas, assuming that the ceiling is ... 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

... 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

... 21. We assume that there are no other forces (like gravity) acting on the test charge. The direction of the electric field line shows the direction of the force on the test charge. The acceleration is always ... 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
