The Poynting vector S⃗ S→S_vec gives the energy flux per unit area of electromagnetic waves. It is defined by the relation S⃗ =E⃗ ×B⃗ μ0S→=E→×B→μ0. Calculate the time-averaged Poynting vector ⟨S⃗ ⟩⟨S→⟩ of the wave considered in this problem.

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 !
