A community with a population of 200,000 in 2015 had a water plant designed to treat 35mgd. If the water use by the community in 2030 is projected to be 140gpcd, will expanded treatment facilities be needed by 2030 when the population is expected to be 260,000? If so, in about what year would they be needed? What reduction in water use rate would be needed to delay the need for new facilities until 2030? Is a reduction of this magnitude attainable?

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
