The Womersley number measured for a hummingbird artery is the Womersley number measured for a human artery. Assume the blood density and viscosity is the same. The diameter of a human artery is 100 times larger than the diameter of a hummingbird artery, but a hummingbird can reach frequencies of pressure 20 times greater than a human can.

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 !

It would stay the same
