The internal resistances of two cells shown are 0.10 and 0.30. If R=0.20, the potential difference across the cell
27, 0.10
27, 0.30

(a)B will be zero
(b)A will be zero
(c)A and B will be 2V
d)4 will be > 21 and B will be <2V

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.
