In a lab, resonance tubes are used to determine experimentally the speed of sound. Using the data given, evaluate the best approximation for the speed of sound.
A) 3x10^8 m/s
B) 170 m/s
C) 340 m/s
D) 570 m/s

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
