A black hole forms when the center of a very massive star collapses in upon itself.
Compound or a simple element.
For example O2 is a chemical formula and represents the element oxigen, because it exists as a diatomic molecule in the air.
NaCl is a chemical formula and represents sodium chloride
CH4 is a chemical formula and represents methane.
Flying animals utilize their wings to create both lift and propulsion by moving them in relation to the body.
<h3>What are living and nonliving things?</h3>
They both consist of fundamentally simple building blocks. They are composed of substance or mass. Atmospheric and molecular building blocks make up the world.
The differences between how living and non-living things fly;
1. Moving both living and non-living objects consumes energy. Flying animals utilize their wings to create both lift and propulsion by moving them in relation to the body.
In contrast to most air vehicles where the components that generate lift wings and thrust engines or propellers are distinct and the wings stay stationary.
Animal aviators like birds as well as natural parachuters like patagial as well as human inventions like aircraft as well as rockets that can power spacecraft and spaceplanes are just a few examples of the many things that can fly.
Hence there are similarities and differences between how living and non-living things fly.
