Janet installed a dimmer on the lights in her bedroom. She slid the dimmer switch, causing the resistance in the circuit to decrease. Assuming the voltage is constant, what effect will Janet’s actions have on the circuit? The voltage will increase from 120 to 240 volts.
The lights will brighten.
The current will decrease.
The current will increase.
The lights will dim.

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.
