Option B is correct. Average speed can be found through the equation speed = distance/time. Applying this to each person using the data in the chart:

Dennis’ speed: 60 ft/0.5 secs = 120 ft per sec

Johnny’s speed: 60 ft/0.45 secs = 133.333 ft per sec

Travis’ speed: 60 ft/0.52 secs = 115.38 ft per sec

Michael’s speed: 60 ft/0.48 secs = 125 ft per sec

As you can see, Johnny’s speed is the fastest at 133.333 ft/sec.

The pOH of a solution is 3.1. Which of the following is true about the solution? (1 point)
Harlamova29_29 [7]

Answer:

<h3>The answer is option B</h3>

Explanation:

To solve the question above we must first find the pH of the solution using the formula

pH + pOH = 14

pOH = 3.1

So we have

pH + 3.1 = 14

pH = 14 - 3.1

pH = 10.9

Since it's pH is 10.9 the solution is a basic solution since it's pH lies in the basic region.

Hope this helps you

The tempertaure at which the pressure of the vapor of a liquid is equal to the external pressure acting on the surface of the li
djverab [1.8K]

Answer: Boiling point

Explanation:

Boiling point is the temperature where the vapor pressure of a liquid equals the pressure of the gas present above it.

The normal boiling point of a liquid is the temperature at which its vapor pressure is equal to one atmosphere.

Boiling point depends on the intermolecular forces present between the molecules. More are the intermolecular forces, lesser will be the vapor pressure and thus more heat will be supplied to make vapor pressure equal to the atmospheric pressure. Thus higher will be the boiling point.

Normal boiling point for water is 100^0C.
