... 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

... 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

... 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

... 31. No. At room temperature, virtually all the atoms in a sample of hydrogen gas will be in the ground state. Thus, the absorption spectrum will contain primarily the Lyman lines, as photons corresponding to ... 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 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

... 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

... For projectile motion the horizontal component of velocity is constant, so at the highest point the magnitude of the velocity cannot be zero, and thus (b) is incorrect.. However, at th[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
