The cheetah can run as fast as 113 km/h, the falcon can fly as fast as 161 km/h, and the sailfish can swim as fast as 105 km/h. the three of them run a relay with each covering a distance l at maximum speed. what is the average speed of this relay team for the entire relay?

answer:

each covers distance l, so a total of 3l, and the time it would take is their maximum velocity/l; 113/l + 161/l + 105/l. i?

the average speed would be equal to one-third the sum of the three speeds as you calculated if the three speeds were each maintained for the same length of time. instead, they are each maintained for the same distance, which will give a slightly different result. given a distance and speed, you can calculate the time.

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
