Consider a river flowing toward a lake at an average velocity of 3 m/s at a rate of 500 m3/s at a location 106 m above the lake surface. determine the total mechanical energy of the river water per unit mass and the power generation potential of the entire river at that location. take density of water to be rho = 1000 kg/m3. (round the final answers to two decimal places.)

Some type of thing that was invisible

Answermake them get very hot and over time wear them out;

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 !
