Answer:
A fundamental theory that provides a description of the physical properties of nature at the scale of atoms and subatomic particles.
Explanation:
Distance=2m
because 200cm = 2m
so 4m-2m=2m
Explanation:
Consider the kinematic equation,

where x is the distance traveled, v is the initial velocity, a is the acceleration and t is time. By plugging in known values and solving for x,

through simple algebra we get

where this is the distance traveled in meters.
