The arrival rate for a certain waiting-line system obeys a poisson distribution with a mean of 0.5 unit per period. it is required that the probability of one or more units in the system not exceed 0.20. what is the minimum service rate that must be provided if the service duration is to be distributed exponentially?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
