Limestone is formed (Chemically) thru calcium carbonate from lake or ocean.
The answer is heat energy
explanation: Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Conduction occurs more readily in solids and liquids, where the particles are closer to together, than in gases, where particles are further apart.
ANSWER
EXPLANATION.
To write in scientific notation means , we write in form,
Where n is an integer and
The given number is,
We move the decimal point backward to obtain our k, the n here is 9, because we moved backward 9 times.
This implies that,
The correct answer is D
Answer:
More than two million electron volts.
Explanation:
More than two million electron volts energy are needed to break or split a deuteron into a proton and a neutron. Nuclear binding energy is the type of energy that is required to split an atom's nucleus into protons and neutrons. The deuteron is an isotope of hydrogen that is composed of a proton and a neutron and it is a stable particle. Very huge amount of energy is needed for the splitting of nucleus due to the presence of heavy particles i.e. proton and neutron.
