Find the equivalent resistance of this circuit. First, what is the equivalent
resistance, Req(23), of the parallel
combination of R2 and R3?
R1 =100 ohm
R2 =200 ohm
R3 =300 ohm
Reg(23) = [?] (in ohms)

The slope of a velocity time graph over any interval of time gives the during that interval

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?

Amoving electron has kinetic energy k1. after a net amount of work w has been done on it, the electron is moving one-quarter as fast in the opposite direction. (a) find w in terms of k1. (b) does your answer depend on the final direction of the electron's motion?
