The average speed

3. 89.7 m/min

4. 6.13 ft/min

<h3>Further explanation</h3>

Given

3. 1076 m in 12 min

4. 92 ft in 15 min

Required

average speed

Solution

3.

<em>I am solving for</em> : the average speed

<em>The equation I need is :</em>

\tt avg~speed=\dfrac{total~distance}{total~time}

<em>This is how I set the equation</em>

<em />\tt avg~speed=\dfrac{1076~m}{12~min}<em />

<em>This is my answer</em> = 89.7 m/min

4.

<em>I am solving for</em> : the average speed

<em>The equation I need is :</em>

\tt avg~speed=\dfrac{total~distance}{total~time}

<em>This is how I set the equation</em>

<em />\tt avg~speed=\dfrac{92~ft}{15~min}<em />

<em>This is my answer</em> = 6.13 ft/min

Answer:

I think it's

there are the same number of molecules on each side of the equation, then a change of pressure makes no difference to the position of equilibrium

List 2 things that about Velocity and Speed that are Different and two that are the same.
frozen [14]
Hey there!
Speed and velocity both:
1) Measure how fast something is moving
2) Both measured in miles per hour, meters/second, etc (rates)
However, there's a prime difference:
Different because:
1) Velocity is speed, but in a certain direction
2) Velocity is a vector
3) Velocity can be positive <em>or</em> negative, unlike speed.
I added another just in case you had a preference :)

Hope this helps!

How do you find the highest energy level?
joja [24]

Answer:

The larger the number of the energy level, the farther it is from the nucleus. Electrons that are in the highest energy level are called valence electrons. Within each energy level is a volume of space where specific electrons are likely to be located.

The [-oh) in a sample of egg whites is 6.3 x 10-7 m. what is the [h3o+] in these<br>egg whites?
Kamila [148]

The hydrogen ion concentration [H3O+] in an egg white containing 6.3 × 10-⁷M of [OH-] is 1.5 × 10-⁸M.

<h3>How to calculate [H3O+]?</h3>

The hydrogen ion concentration of a solution can be calculated as follows:

pOH = - log [OH-]

pOH = - log [6.3 × 10-⁷M]

pOH = - [-6.2]

pOH = 6.2

Since pOH + pH = 14

pH = 14 - 6.2

pH = 7.8

pH = - log [H3O+]

7.8 = - log [H3O+]

[H3O+] = 10-⁷:⁸

[H3O+] = 1.5 × 10-⁸M

Therefore, the hydrogen ion concentration [H3O+] in an egg white containing 6.3 × 10-⁷M of [OH-] is 1.5 × 10-⁸M.
