Aperson riding north on a bicycle speeds up from 0m/s to 9m/s in 3 seconds. the acceleration of the bicycle is

Acceleration = (change in speed) / (time for the change)

                     = (9 m/s) / (3 sec)

                     =   3 m/s²

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 !
