When an initially uncharged capacitor is charged in an RC circuit, what happens to the current in the circuit? It is initially at its maximum value and then decreases linearly with time. It is initially 0 and then increases linearly with time. It is initially at its maximum value and then decreases exponentially with time. It is initially 0 and then increases exponentially with time. It is constant during the charging.

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.
