In the qualifying round of the 50-yard freestyle in the sectional swimming championship, dugan got an early lead by finishing the first 25.00 yards in 10.01 seconds. dugan finished the return leg (25.00 yard distance) in 10.22 seconds. determine dugan's average velocity for the entire race.

=  2.471  yards/s

Explanation:

We can calculate the average velocity thus:

Where

              : First 25 yards

              : Time to travel  

              : Seconds 25 yards

              : Time to travel  

Thus

=  2.471  yards/s

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
