Aradio antenna broadcasts a 1.0 mhz radio wave with 30 kw of power. assume that the radiation is emitted uniformly in all directions. part a what is the wave's intensity 33 km from the antenna? express your answer in watts per meter squared. ii = nothing w/m2 request answer part b what is the electric field amplitude at this distance? express your answer in volts per meter. ee = nothing v/m

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.
