Matter when broken down into its simplest parts forms elements. These are pure substances that everything in the universe is composed of. The smallest unit of an element is an atom, and when two or more atoms combine, a molecule is formed.
When matter is broken down into its simplest parts, it forms elements. Elements are the pure substances that everything in the universe is composed of and they cannot be broken down further using ordinary chemical reactions. Examples of elements include hydrogen, oxygen, carbon, nitrogen, calcium, and iron.
The smallest unit of an element is an atom, which is made up of subatomic particles like protons, electrons, and neutrons. When two or more atoms combine, a molecule is formed. Molecules are the smallest particles of matter while still retaining their chemical properties.
Elements in nature are unique with specific chemical and physical properties. Currently, 118 elements are known, but only 98 occur naturally. The remaining are synthesized in laboratories due to their instability.

Answer:
a lightweight foam insulation
Explanation:
converts sound waves into electrical signals
removes high and low sound waves that are harmful
transmits sound waves from air to fluids
Answer:
The ossicles amplify the sound. They send the sound waves to the inner ear and into the fluid-filled hearing organ (cochlea). Once the sound waves reach the inner ear, they are converted into electrical impulses. The auditory nerve sends these impulses to the brain.
Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The bones in the middle ear amplify, or increase, the sound vibrations and send them to the inner ear—also called the cochlea—which is shaped like a snail and is filled with fluid.
Answer:
its (A) trust me I had that same qeu
Explanation:
42,256 = 2,000
42,256 = 200
together they'd be 2,200 (if that's what you needed as well)
Explanation:
Using the Newton's laws, we can find the force F required for lifting the book having mass (m) and acceleration due to gravity (g) that is ;
and, the change in the position of the book that is Δx (Height)
→ Δx = Final position - Initial position
which is only the height, then the amount of work done will be calculated by :
W= mgh
m = Mass of the Body
g = Acceleration due to Gravity
h = Height of Body being displaced
