A32% efficient electric power plant produces 900 mj of electric energy per second. waste heat is discharged into the ocean at 20° c. some systems use waste heat to heat homes in the winter. assume the average american house uses 23 kw of heating.

70 give a real life example showing how sensory neurons work with the motor neurons

What sort of waves exhibit the doppler effect?

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.
