Afuse is used to protect electric circuits from too much electricity running through them. how should a fuse be hooked up with the components it is designed to protect? justify your answer. a) a fuse should be hooked up in series because all the current must flow through the fuse in a series circuit. b) a fuse should be hooked up in parallel because all the voltage must flow through the fuse in a series circuit. c) a fuse should be hooked up in parallel because all the current must flow through the fuse in a parallel circuit. d) a fuse should be hooked up in parallel because all the voltage must flow through the fuse in a parallel circuit. it was a

Wo audio speakers are placed on a vertical rail. speaker a is placed at head-level while speaker b is place at some variable height, \delta yδy, above speaker a. both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.531 meters. calculate the lowest height that speaker b can be placed above speaker a to produce a minimum of sound heard by person standing \delta x = 7.86δx=7.86 meters directly in front of speaker a.

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.
