A small rectangular object of unknown material is examined in the laboratory. Iron filings and a compass needle are not attracted to the object. The object is suspended from a light string and is free to swing but does not align itself with Earth’s magnetic field. A strong magnetic field is switched on perpendicular to the long axis of the object. The object changes its orientation so that it partially aligns with the magnetic field. After the field is switched off, the object and string eventually return to their original orientation. Once again, it is observed that iron filings and a compass needle are not attracted to the object. The object most likely is exhibiting the property of

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.
