If the velocity of the car is 39 m/s, then how long does it take the car to travel 400m?

10.25 seconds

Explanation:

Divide 400/39, leaves you with how many seconds it takes to travel that distance.

It's nice that this problem has everything in meters already, so that you don't have to do any unit conversions.

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

technology is the application of the knowledge gained by science.
