Water at 20 c flows steadily through the box in fig. p3.56, entering station (1) at 2 m/s. calculate the (a) horizontal and (b) vertical forces required to hold the box stationary against the flow momentum. water at 208c flows steadily through the box in fig. p3.56, entering station (1) at 2 m/s. calculate the (a) horizontal and (b) vertical forces required to hold the box stationary against the flow momentum.

Newtons laws of motion

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 !
