Answer: Kalium Argon dating
Kalium or Potassium radioactive atom that commonly found in stone or artifact. Since Kalium is radioactive, it will be reduced and converted into another atom(in this case argon) after a set of time. You can determine the time elapsed by comparing the Kalium with argon mass.
Answer:
750 kg.m/s
Explanation:
Momentum is the product of mass and velocity in kg.m/s.
In this case, initial momentum⇒p=m × v where m is mass and v is velocity
initial mass of car m₁=100 kg
Initial velocity of car v₁=5 m/s
Initial momentum= 100×5= 500 kg.m/s
New mass after picking two extra people m₂= 150 kg
Velocity stays the same v₂=v₁= 5 m/s
New momentum= m₂× v₂
p=150×5=750 kg.m/s
The name Morpho refers to the butterfly's genus name. The genus name is a taxonomic category that is ranked above the species name and below the family name. The name morpho means changed or modified which applies the the way a lava undergoes metamorphosis and changes into a butterfly. Most morpho butterflies have a colour of metallic, shimmering shades of blue and green.
Answer:
Atoms are the most basic units of an element whereas molecules are atoms that are chemically bonded together.
Explanation:
- The atoms are made up of protons, neutrons, and electrons that are the basic constituents of matter.
- The atoms occur in nature as single or bonded.
- The inert gases are the atoms that they occur as the individual atoms in nature.
- All other atoms in nature are bonded to the same elements or different elements and form molecules.
- Hence, atoms are the most basic units of an element whereas molecules are atoms that are chemically bonded together.
