The distance between two successive minima of a transverse wave is 2.76 m. Five crests of the wave pass a given point along the direction of travel every 14.0 s. Find (a) the frequency of the wave and (b) the wave speed.
Week 9 Tuesday, October 18, 2016 11:03 AM Junction rule- sum currents entering any junction must = sum current leaving that junction ○ # times can be used is # junctions in the circuit-1 Loop rule- sum of potential diff across all elements around any closed circuit loop must be 0 ○ Can make loop through circuit where all connected(in triangle pattern) Ex) loop acda: Vca+Vsc+Vad=0 (so does loops cbdc) (& acbda) ○ You need as many indep eq as you have unknowns ○ Can be used so long as new circuit element(resistor or battery) or new current appears in each new equation ○ Can be used #loops-1 times ○ Ex) going around loop from a to b for loop, det Vi if resistor is transversed in dir of cu
