Electricity can be produced from a variety of fuels and methods.
(a) Although producing electricity from burning fossil fuels, such as in coal-fired power plants, is common around the world, some scientists and economists argue that where the geography is appropriate, hydroelectric power is a better method for generating electricity.
(i) Describe one advantage of using hydroelectric power plants over using coal-fired power plants.
(ii) Describe one potential disadvantage of hydroelectric power plants.
Explanation:
i) as we know fossil fuels are the main cause of pollution in most parts of the world. So hydroelectric power plant are useful as they do not cause pollution and they are environment friendly because it is produced by water.
ii) Dams can help in i) Increase Tourism

Assume the economy is currently in long-run equilibrium. An increase in the money supply will affect unemployment in the short run and in the long run in which of the following ways?
A money supply go up and be inflationary in nature if the unemployment rate is below the natural rate and thus there will be high rate of unemployment.
What does it implies when the economy is in long run equilibrium?An economy that is to be in long-run equilibrium will have the real unemployment rate to be equal to that of natural rate of unemployment.
Note that a boast in the money supply will influence unemployment based on the fact that unemployment rate is bigger than the natural rate of unemployment, and thus the rate of inflation is said to be going done.
When the level of output is higher than employment output, an unemployment rate tends to increase and thus pressure is placed on increased wages and prices.
Conclusively, Note that Lower unemployment rate will lead to lower presence of workers in the companies .

A. Government regulations increase the cost of making the product.
B. New technology allows the product to be made more quickly.
C. Companies expect the price of the product to fall significantly.
OD. Fewer workers receive the education needed to create the product.
SUBMIT
Answer:
B: New technology allows the product to be made quicker
If a product can be made quicker, you can make more products in less time, resulting in more supply/stock.
New technology allows the product to be made more quickly. The correct option is B.
What is technology?The tools, methods, and systems used to create, process, store, and exchange information, or to perform tasks that make life easier and more efficient, are referred to as technology.
Because it improves the efficiency of the manufacturing process, the development of new technology that allows a product to be manufactured more quickly can increase the supply of that product.
Lowering production costs can make it more profitable for producers to supply more product to the market.
As a result, they may increase production to meet rising demand or to take advantage of lower production costs, resulting in an increase in product supply.
Thus, the correct option is B.

The t-test tests for:
The t-test is a statistical test used to determine if there is significant statistical evidence for a difference in means between two groups.
Essentially, what this means is that it's used to figure out whether or not two groups have different means. When we run a t-test, it returns to us a t-score and a P-value. P-value is derived from the t-score, and this P-value is essentially the probability that the null hypothesis would produce the observed results displayed in the question. In order to determine if we should reject or fail to reject our null hypothesis, the P-value determined by the t-test should be lower than the significance level. If the question doesn't prompt for a specific significance level (which is usually displayed symbolically as α), then we can generally use 0.05 as the significance level.
I'll admit, this whole concept is pretty confusing. Statistics is a surprisingly hard class. If you have any questions about anything I wrote here or would like me to explain any concept I mentioned further, don't be afraid to ask me!

What is t-interval?When the sample size is small and the population standard deviation is unknown, the T interval is useful.

A multi-state nation occurs when a nation stretched across international borders, therefore across states
China - currently a mutli-state nation:
The Nationalist party in China fought against communist forces before and after WWII but by 1949 the Communist under Mao Zedong won. The Nationalists then fled to Taiwan and claimed they were the legitimate government of China. Today, 95% of people who lin in Taiwan are Han Chinese. Therefore, the people or nation (the Chinese) are split between China and Taiwan.
Ireland - currently a mutli-state nation:
The Irish War of Indepence took place from 1919 to 1921 and resulted in Ireland’s independence from the U.K along with Ireland becoming split. In 1921 Northern Ireland was created when Ireland was partitioned by the Government of Ireland act of 1920. The majority of Northern Ireland’s population were unionists who wanted to remain with the U.K. and this act created a devolved government for the 6 northeastern counties. Today, the Irish people are divided between the Republic of Ireland and Northern Ireland which is still part of the U.K.
Germany - was a mutli-state nation in the past:
After WWII the eastern part of Germany including the 5 landers of Brandenburg, Mecklenburg-Vorpommern, Saxony, Saxony-Anhalt, and Thuringia was occupied by Soviet forces. In 1949, Germany formally split into 2 independent states: The Federal Republic of Germany (West Germany - democracy) and The German Democratic Republic (East Germany - communist). In 1961 the GDR/East Germany built the Berlin wall overnight on August 13, creating a physical border between East and West Germany. In 1989 communism fell in East Germany and the Berlin Wall was torn down the same year. The country was reunified in 1990.
Vietnam - was a mutli-state nation in the past:

2. Which statement is a complex sentence?
After the storm subsided, I surveyed the house for damage. O
I really wanted to go to my friend's house, but I stayed home.
The house sustained some damage as a result of the storm. O
I brought lumber to fix the damage; my father brought tools.
Answer:
A.
Explanation:
1. Complex sentence: Has one independent clause and 1 (or more) dependent clauses
2. Clause: Contains a subject and verb
3. Independent Clause: Taking the clause out of the sentence would make sense as a sentence on its own.
4. Dependent Clause: Even though it has a subject and verb, it doesn't make sense as a sentence.
Not B: This is a compound sentence. It has 2 independent clauses. I know this because If you take "I really wanted to go to my friend's house" and "I stayed at home," they can be their own sentence.
Not C: This is similar to a complex sentence, so it can be trickier. It's not because "as a result of the storm" doesn't have a subject or verb so it's nto a clause.
Not D: Before and after the semicolon can be their own sentence. Because they're both independent, it's compound and not complex.
It's A: "After the storm subsided" doesn't make sense by itself, but it has a subject (storm) and verb (subsided). That makes it dependent. The other is independent because it makes sense as a sentence. Independent clause+dependent clause= complex.
