Examine the scenario. an object is placed in a magnetic field where its magnetic domains are aligned. it is then removed from the magnetic field and heated. its magnetic domains are now random. which choice correctly describes the object?

the object is a temporary magnet because its domains become random when heated and removed from the field. temporary magnets require both of these actions to happen in order to randomize its domains.

the object could be a temporary or permanent magnet. the domains in temporary magnets become random if taken out of the field. the domains in permanent magnets can become random if heated.

the object is neither a permanent or temporary magnet because it could not maintain the alignment of its magnetic domains.

the object is a permanent magnet because its domains became random when heated and removed from the field. permanent magnets have random domains if either of these actions happen.

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.
