Explanation:
When salt dissolves in water, it comes apart into ions with positive and negative electrical charge. That's actually what we mean by calling a material a salt. Ordinary table salt forms Na+ and Cl-. These charged particles are dragged opposite ways by an electrical field, making an electrical current. So that's how salt water conducts.
Water is one of the most powerful forces on earth. How does the example shown here illustrate the theory of uniformitarianism?
The image illustrates the theory of uniformitarianism by; showing us the erosion activity of land in past and present scenarios.
What is uniformitarianism?The theory of uniformitarianism is the principle given by the Scottish Geologist Hutton that says that the present is the mirror to the history and the geological evolutions of the past eras.
Thus, the principle states that the geological process is continuous and constant rather than being broken or discontinuous.
The image attached shows the soil erosion process of the land and this tells us that the erosion even happened in earlier times on that land and still in the present time the process is continuously going on.
Therefore, the image illustrates the theory of uniformitarianism by showing us the erosion activity of land in past and present scenarios.

1. This composite figure is created by placing a sector of a circle on a rectangle. What is the area of this composite figure? show you work.
The total area of the composite figure is; 142.12m²
How to find the area of a Composite Figure?For the rectangle, we are given;
length = 14m
width = 6m
Thus;
Area of rectangle = length x breadth
Area = 14 x 6
Area = 84m²
Now, For the sector of the circle, we are given;
θ = 34°
radius; r = 14m
Thus;
Area of the sector = (θ/360) * π * r²
Area of sector = 34/360 * π * 14²
Area = 58.12 m²
Total area of composite figure = 84 + 58.12 = 142.12m²

A gas that has a volume of 28 liters, a temperature of 450c, and an unknown pressure has its volume increased to 34 liters and its temperature decreased to 350c. If i measure the pressure after the change to be 2. 0 atm, what was the original pressure of the gas?.
Answer:
2.82 atm
Explanation:
Initial:
V1 = 28 liters, T1 = 450 C = 450 + 273 K = 723 K, P1 = ?
Final:
V2 = 34 liters, T2 = 350 C = 350 + 273 K = 623 K, P2 = 2.0 atm
Use P1 * V1 / T1 = P2 * V2 / T2
so P1 = P2 * (V2/V1) * (T1/T2) = 2.0 * (34/28) * (723/623) = 2.82 atm

Triangular island has a lighthouse at each of its corners, represented by the vertices of the triangle. The perimeter of triangular island is 6. 8 miles. There is a channel on triangular island which divides it into two smaller islands: green island and coconut island. The length of the channel is equal to half of the distance between the lighthouses on coconut island. What is the perimeter of green island.
The perimeter of the green island is; 3.4 miles
How to find the Perimeter of a Triangle?
We are given;
Perimeter of triangular Island = 6.8 miles
A channel divides the triangular island into 2 smaller islands.
Now, we are told that this channel is half the length of the distance between the lighthouses.
If the distance from one light house is x, the length of the channel is x/2.
Thus;
The channel cuts horizontally and green island is a small triangle while coconut island is a trapezium.
Since perimeter of the main triangular island is 6.8 miles, then;
3x = 6.8
x = 6.8/3
x = 2.267 miles
Then the perimeter of green island = (2.267/2) + (2.267/2) + (2.267/2) = 3.4 miles

In this experiment, you will use universal indicator to qualitatively measure ph. The universal indicator in this experiment is a mixture of 4 common indicators allowing for a large ph range to be measured. The following table (also available in your lab manual) describes the individual components of our universal indicator.
The true statements is that the color of the indicator relates to the hydrogen ion concentration of the solution.
What does the color change tell you about the pH?If a solution is acidic or basic, it can be measured using the pH scale. The universal indicator is said to be added into a specific solution, the color change therefore shows the estimate of the pH of the solution.
An Acid often makes universal indicator solution to change from green toward red and their solution's pH is one that is below 7 on the pH scale.
Note that pH indicators are said to be weak acids and they show the concentration of H+ (H3O+) ions in a solution through color change.
See options below
Select all of the following statements that are true about the universal indicator used in this experiment
The color of the indicator relates to the hydrogen ion concentration of the solution.
At pH 7 the indicator will be colorless.
The universal indicator (or parts thereof) are in equilibrium and have an associated K value.
The color of the indicator relates to the neutral ion concentration in solution.
The universal indicator is a single chemical compound.

Frank, who lives in texas, and his sister lilly, who lives in japan, correspond regularly. From what he can tell from the postmarks on both his and his sister’s letters, it appears that it takes longer for lilly’s mail from japan to reach him in texas than it does for his letters from texas to reach her in japan. When frank called his post office to ask if there was a reason for this, the postmaster told him that the delivery time of letters in both directions should be the same. Frank and his sister decided to collect data to see if letters from japan to texas take longer to be delivered than letters from texas to japan. They recorded the delivery time in days. After convincing themselves that the assumptions were reasonable, they performed a two-sample t-test and obtained the following computer output.
Answer:
(A) There is convincing evidence that there is no difference in the mean delivery times.
(B) There is convincing evidence that there is a difference in the mean delivery times.
(C) There is convincing evidence that the mean delivery time from Japan to Texas is greater than the mean delivery time from Texas to Japan.
(D) There is not convincing evidence that the mean delivery time from Japan to Texas is greater than the mean delivery time from Texas to Japan.
(E) The t-test cannot be used for sample sizes that are this small.
Explanation:
The correct option is;
(A) There is convincing evidence that there is no difference in the mean delivery times.
Step-by-step explanation:
Here we have the formula for the two-sample t-test given s;
To Texas N₁ = 12, =8.74 σ₁ = 2.92 SE Mean₁ = 0.84
To Japan N₂ = 9 = 6.75 σ₂ = 2.56 SE Mean₁ = 0.85
t = 1.667
Where the null hypothesis is
mu To Texas = mu To Japan and the alternative is
mu To Texas > mu To Japan
Here since the observed P value of P = 0.058 is greater than the significance level of 0.05 we fail to reject the null hypothesis and we will therefore, not accept the alternative hypothesis.
Hence, there is convincing evidence that there is no difference in the mean delivery times.
