The moon has an acceleration due to gravity of -1.6 meters per second. A 1,100-kilogram space rover travels on its surface at 3.2 meters per second. What is the approximate magnitude of the normal force acting on the vehicle? 1800N or 340N

The answer is -6.4

Explanation:      

frequency or wavelenth of em radiation in a vacuum

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
