Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, and is the primary interaction occurring in ionic compounds.A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

Acceleration is defined as the rate of change of velocity.
A. the same speed as the wave energy
Answer:
infra red radiation is used
8/4 = y/y-x
8y - 8x = 4y
y = 2x
y = 2 x 4
y = 8
