Answer: optio C. 6.

pH measures the acidity of the solutions.

pH 2 is highly acid and pH 12 is highly basic (alkalyne).

You can be sure that the pH of the solution will be intermediate between 2 and 12.

Given that the volumen of the two solutions are equal the pH of the resulting combination cannot be so close to the original solutions. That takes you to eliminate all the options except the option C. 6.

You cannot be sure that the final pH will be 6, because that will depend on the stregths of the two original solutions, that is why the question asks for the most likely resulting pH, and the answer is optio C. 6.

Why can acceleration include only a change in direction?
Fynjy0 [20]

First we shall look at some terms:

Velocity - frequency of change of an objects position.

Acceleration - frequency of change of an objects velocity


Since velocity covers both change in direction and speed, we can asume that the answer is B, not because it's the only one we worked with, but because the others don't make any sense:

A - this is not correct, because a chnage in direction can be done withough a change in speed.

C - The scientific definition of acceleration does include speed, and this is not a reasonable answer.

D - Velocity can change, unlike said in the sentence.


Hope it helped,

Given an object's mass and observing its acceleration, what can be found in a direct application of Newton's second law of motio
Natalka [10]

Answer:

C. the net force on the object

Explanation:

That is because Force= mass x acceleration. The question says that we know the mass and acceleration, which means that it would be the force that resulted in the acceleration of the mass.

A rocket is launched and the observer measuring the rocket altitude is standing at a distance of 200 feet from the launcher. Whe
Gre4nikov [31]

Answer:

100 foot

Explanation:

Using the formula for calculating range to calculate the speed first as shown;

<h3>Range R = U²sin 2theta/g</h3>

U is the speed

theta is the observe angle

g is the acceleration due to gravity.

200 = U²sin 2(45)/9.8

Usin90 = 200 * 9.8

U² = 1960

U = √1960

U = 44.27 m/s

Get the required altitude

Altitude H = u²/2g

H = 44.27²/2(9.8)

H = 1,959.8329/19.6

<em>H = 99.99 feet</em>

<em>Hence the altitude of the rocket to the nearest foot is 100 foot</em>
