in a transistor amplifier, when the signal charges by 0.02V, the base current changes by 10MA and collector current 12IMA. if collector load RC=5Kohms and RL=10Kohms, find (1) current gain (2) input Impedance (3) A. C load (4) Voltage gain (5) power gain

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage

For this car, predict the shape of a graph that shows distance (x) versus time (t). note that time is the independent variable and will be on the bottom axis. need asap
