Why do distance v. time graphs not need a reference point?
JulijaS [17]

Answer:

When an object moves, we often refer to the amount it moves as the distance. Distance does not need a reference point and does not need a direction. If an automobile moves 50 kilometers, the distance traveled is 50 kilometers regardless of the starting point or the direction of movement.

Find the pH of HCl with a concentration of 0.00006M<br> Round to the nearest whole number
Tpy6a [65]

Answer:

4.22

Explanation:

pH stands for potential hydrogen. The letter “p” denotes potential and the letter “H” denotes hydrogen.

pH helps to find the acidity or alkalinity of an aqueous solution.

The number of hydrogen ions (protons) present in a solution is determined by the pH scale.

A pH greater than 7 makes the water more alkaline and a pH less than 7 makes the water more acidic.

pH=-\log [H^+]=-\log [0.00006]=4.22
