When a spring vibrates, it does so with a steady pattern. The time it takes to complete One cycle of this vibration is known as the ___ of the spring.

Period of vibration

Explanation:

The period of vibration of the spring is defined as the time taken by the spring to complete one complete cycle of motion. One complete cycle of motion involves stretching and returning of spring to its original position.

The frequency of motion is defined as the number of cycles completed in one unit time.

Thus period has a inverse relationship with frequency of the spring and is represented as

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
