Dalton's Atomic Theory had several main points, which are variously grouped into five statements : 1) All matter is made of atoms. 2) Atoms of a given element are identical in size, mass and chemical properties. 3) Atoms of different elements have different masses and properties.
Distance covered along the slope is 48 m
Explanation:
A uniform motion is a motion in which the velocity is constant. The distance covered by an object during a uniform motion is given by
where
v is the velocity
t is the time
Here we have:
v = 0.8 m/s (velocity)
t = 1 min = 60 s
Therefore, the distance covered along the slope is:
