In thi is exercise, we examine in detail how an instruction is executed in a single-cycle datapath. problems in this exercise refer to a clock cycle in which the processor fetches the following instruction word: oxf80140f2. what are the outputs of the sign-extend and the "shift left 2" unit (near the top of figure 4.23) for this instantaneous word? what are the values of the alu control unit'sinputs for this instruction? what is the new pc address after this instruction is executed? highlight the path through which this value is determined. for each mux, show the values of its inputs and outputs during the execution of this instruction. list values that are register outputs at reg [kn. what are the input values for the alu and the two add units? what are the values of all inputs for the register unit?

Dinate system, and a charge q = - 2.00 nc is placed s2 10 n> c. (a) what is the change in electric potential energy when the dipole moment of a molecule changes its orientation with respect to es from parallel to perpendicular? (b) at what absolute temperature t is the average translational kinetic energy 32 kt of a molecule equal to the change in potential energy calculated in part(: abovethistemperature,thermalagitationprevents the dipoles from aligning with the electric field.) placed in a uniform electric field e with magnitude 1.6 * 6 on the positive x-axis at x = 4.00 cm. (a) if a third charge q3 = +6.00 nc is now placed at the point x = 4.00 cm, y = 3.00 cm, find the x- and y-components of the total force exerted on this charge by the other two. (b) find the magnitude and direction of figure p21.62 ll uu 21.55 . torque on a dipole. an electric dipole with dipole moment ps is in a uniform external electric field es. (a) find the orientations of the dipole for which the torque on the dipole is zero. (b) which of the orientations in part (a) is stable, and which is unstable? (hint: consider a small rotation away from the equi- librium position and see what happens.) (c) show that for the stable orientation in part (b), the dipole’s own electric field tends to oppose the external field. 21.62 ..

Awhite-blue star is hotter than a red star. select the best answer from the choices provided true or false

Which of the following conditions lead you to see an absorption line spectrum from a cloud of gas in interstellar space? the cloud is extremely hot. the cloud is visible primarily because it reflects light from nearby stars. the cloud is cool and lies between you and a hot star. the cloud is cool and very dense, so that you cannot see any objects that lie behind it.
