You have covered a grounded metal surface with a layer of photoconductor. working in the dark, you sprinkle negative charge onto this surface. if you now expose only the left half of the photoconductor to light, you will find that
(a) the left half becomes neutral while the right half remains negatively charged.
(b) nothing happens because there is no changing magnetic field.
(c) negative charge flows from the right side of the photoconductor to the left and both sides become neutral.
(d) the right half becomes neutral while the left half remains negatively charged.

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
