When point charges q = +8.4 uc and q2 = +5.6 uc are brought near each other, each experiences a repulsive force of magnitude 0.66 n. determine the distance between the charges. ns

What component of earth’s atmosphere exists entirely as a result of photosynthesis?

The three classes of rocks are sedimentary, metamorphic, and igneous. how are rocks classified into one of these three groups?

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.
