Choose the best description of the radial velocity method of locating exoplanets. The orbiting planet causes the star to wobble causing it to appear bluer or more red depending on which direction it moves.

This method is works well for detecting planets orbiting in close proximity to a star, so the planet can more readily observed passing in front of the star.

Planets are timed as they orbit distant stars. The size of the planet can be judged by time duration it takes to transit a star.

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.
