If motion starts and stops at the same place is this distance zero ?

Shtirlitz [24]

Displacement is zero. Displacement is in reference to the starting and ending positions, so starting and ending in the same place would cause a net displacement of zero. Distance, however, is not zero. It is a measurement of the total amount moved, so if the object left the starting position, the distance is automatically not zero.

Which statement best describes the pH of pure water?

Ray Of Light [21]

The pH of pure water is neutral because the concentration of hydronium ions equals that of hydroxide ions.

Answer: Option A

<u>Explanation:</u>

Water is one of the most important constituents of living being. It is said that there is no life without water. So that water need to neutral in nature to save life. Pure water is composed of hydronium $H^{+}$ and hydroxide $\left(O H^{-}\right)$ ions. It is known that hydronium ions are acidic in nature with concentration of $1 \times 10^{-7} \mathrm{M} / \mathrm{L}$ .

Similarly, the hydroxide ions which are basic in nature will be in same concentration as that of hydronium ions. So, as the concentration of basic and acidic elements are equal with the same strength of pH, the combination of these ions lead to formation of pure water with the pH being neutral.
