It is suggested that the mass flow rate Q of grains through a hopper can be given by Q - Cp[(g)^(1/2)] [( D- kd) ^(3/2)]
Where C and k are constants ; p is the density of the grains , D is ine diameter of the hoppers
d is the diameter of the circular grain and g is the acceleration due to free fall
Determine the units of C and k in terms of SI base units

The answer is: 6.3mi got it right

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 !
