Answer:
Atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry.
Atom: has equal number of +ve charge (protons) and -ve charge electrons and hence atom has charge.
Neutrons (having no charge) and protons are present in nucleus. Electrons keep revolving around the nucleus in different shells.
Adhesion of water to the surface of a material will cause an upward force on the liquid. The surface tension acts to hold the surface intact. Capillary action occurs when the adhesion to the surface material is stronger than the cohesive forces between the water molecules.
The original location of an earthquake is known as the epicenter.
Answer:
27 days
Explanation:
It takes 27 days, 7 hours, and 43 minutes for our Moon to complete one full orbit around Earth. This is called the sidereal month, and is measured by our Moon's position relative to distant “fixed” stars. However, it takes our Moon about 29.5 days to complete one cycle of phases (from new Moon to new Moon).
