In the Bohr model of the hydrogen atom, an electron in the 4th excited state moves at a speed of 1.37 x 105 m/s in a circular path of radius 8.46 x 1010 m. What is the effective current associated with this orbiting electron? 4.1 Your response is off by a multiple of ten. mA
Figure a shows a rod of resistive material. The resistance per unit length of the rod increases in the positive direction of the X axis. At any position x along the rod, the resistance dR of a narrow- differential-section of width dx is given by dR = 5.00xdx, where dR is in ohms and is in meters. Figure b shows such a narrow section. You are to slice off a length of the rod between X = O and some position = L and then connect that length to a battery with potential difference V = 5.0V (Fig. c). You want the current in the length to transfer energy to thermal energy at the rate of 6.2 W. At what position x = L in meters should you cut the rod?
