An amplifier with 40 db of small-signal, open-circuit voltage gain, an input resistance of 1 m, and an output resistance of 100 , drives a load of 500 . what voltage and power gains (expressed in db) would you expect with the load connected? if the amplifier has a peak output-current limitation of 20 ma, what is the rms value of the largest sine-wave input for which an undistorted output is possible? what is the corresponding output power available?

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2
