Hey mates. i need this answered asap! question one (1 point) what is it called when the crest of one wave meets the trough of another wave and they cancel out? a) constructive interference b) destructive interference c) wave length d) wave speed i missed class and i am new to this. !

Your answer is B. destructive interference

What formula  this one  (x_/

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 !
