Answer:
Option (B)
Explanation:
To measure the distance between two objects we use the units of length.
To measure small distances we use, mm or cm or m. But if we measure large distances between two objects we use large units such that kilometer or miles.
To measure the very large distances between two objects we use large units such as Astronomical unit or Parsec.
The Astronomical unit is defied as the distance between earth and Sun.
Thus, the distance between earth and the sun is defined as 1 Astronomical unit.
1 Astronomical unit = 1 A.U. = 1.5 x 10^8 km = 1.5 x 10^11 m
Each element is made up of only one kind of atom.
Each element has their own atom.
Still go straight but would obviously go up in speed!!

Since the grains are not connected together, it's every grain for himself when they're dropped into the water.
The density of each grain is greater than the density of water, so each grain on its own sinks to the bottom.
The reason why a CUP or a BAG of rice has less density is because the grains don't all fit together perfectly, and 15% or 20% of the volume in the cup or bag is air, not rice grains.
