-BARSIC- [3]
10 km/h

Because if you take 35 and multiply it by 2, and take 0.5 and multiply it by 2, you get 70 kilometers in 1 hour. Therefore, 70-60 is 10 km/h

Is a solution in which (OH) = 1.0 10-1M acidic, basic, or neutral?
astra-53 [7]

Answer:

The pH is 13,00 and the solution is basic.

Explanation:

<em> </em>The pH indicates the acidity or basicity of a substance. PH values between 0 and less than 7 indicate acidic solutions, 7 neutral and higher than 7 to 14 basic. It is calculated as

pH = -log (H 30+)

Both pH and pOH have a relationship to belonging to the same aqueous solution: the expression of the Kwater (ionic product of the water Kw) is used:

[H3O ^ +]x [OH ^ -] = 1x 10 ^ -14

[H3O ^ +]x [1.0 10-1]=1x 10 ^ -14

[H3O ^ +]= 1x 10 ^ -14/1.0 10-1M= <em>1.0 10-13 M</em>

pH = -log (H 30+)= -log (1.0 10-13 M)= <em>13, 00</em>

As the pH value is higher than 7, it corresponds to a basic substance.

shtirl [24]

Answer:

Kindly check explanation

Explanation:

The force applied is directly proportional to the distance moved by an object, the larger the applied force, the greater the distance moved.

a = f/m

a = acceleration ; f = applied force ; m = mass

From the relation, we can see that acceleration is directly proportional to force applied.

The ball will travel farthest with the greatest applied force while, nearest distance will be attained with the smallest applied force.

The distance covered is affected by both the mass of the object and the applied force

The __________________variable is the one factor you manipulate or change in the experiment
SVEN [57.7K]
The independent variable is the one factor you manipulate or change in the experiment.


The dependent is what you are measuring. The independent is the one thing you are altering so you can carry out your experiment.
