What are smaller than cells but larger than atoms?
Molecules are smaller than cells but larger than atoms. They are composed of atoms bonded together to form a distinct structure.
Are comets smaller than a grain of sand?
No. Comets are usually a few thousand feet to a few miles wide. An object smaller than a sand grain would not be visible in space.Meteors which enter the earth's atmosphere are often sand grain sized, but the once we can see are usually from pebble sized objects.
Are the atoms of potassium larger than the atoms in calcium?
yes
Which sediment grains sink faster pebbles or sand grain?
Pebbles sink faster than sand grains due to their larger size, weight, and density. The larger surface area of pebbles compared to sand grains experiences less resistance as they sink through the water, allowing them to fall more quickly. Sand grains, being smaller and lighter, have a larger surface area that creates more friction with the water, slowing down their sinking rate.
Is a googol larger than all of the atoms in the universe?
Yes, a googol is larger than the estimated number of atoms in the observable universe. A googol is 1 followed by 100 zeros, while the estimated number of atoms in the observable universe is around 10^80.
