Can please tell what mistake I did??question number 10

Explanation:

When we draw the diagram of the motion we get a right angled triangle.

We have an angle of 30° and a base of 17.3M.

We will use trigonometric ratios to solve this.

We will use tan.

Tan = Opposite / adjacent

Tan 30° = h / 17.3

h = Tan 30 × 17.3

h = 0.5774 × 17.3 = 9.99 M

or 9.99 can be roundoffed with 10m

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
