The order of discovery for the types of radiation is as follows:

1. Infrared radiation (discovered in 1800 by William Herschel)
2. Ultraviolet radiation (discovered in 1801 by Johann Wilhelm Ritter)
3. X-radiation (discovered in 1895 by Wilhelm Conrad Röntgen)
4. Gamma radiation (discovered in 1900 by Paul Villard)

Explanation: Infrared and ultraviolet radiation were identified in the early 19th century, while X-rays were discovered later in the 19th century, followed by gamma rays in the early 20th century. Each type of radiation was found through various experiments and advancements in scientific knowledge. If you have more questions or need further assistance, feel free to ask!

Let’s simplify the given expression step by step:

1. Start with the first part of the expression:

[(9 × 10^6) / (1 × 10^{-8})]

When dividing, you can subtract the exponents:

[

= 9 × 10^{6 – (-8)} = 9 × 10^{6 + 8} = 9 × 10^{14}

]

2. Now, we’ll add the second part of the expression:

[9 × 10^{14} + (3 × 10^{-8})]

Since (10^{-8}) is much smaller than (10^{14}), you can ignore it for the sake of addition. However, if you want to express everything in the same power of ten, we would convert (3 × 10^{-8}) to the same base:

[

= 9 × 10^{14} + 0.00000003 × 10^{14} = 9 × 10^{14} + 0.00000003 × 10^{14} = (9 + 0.00000003) × 10^{14} approx 9 × 10^{14}

]

Therefore, this addition does not significantly change the result.

3. As a result, the simplified expression approximately equals (9 × 10^{14}).

Given the

The correct answer is taxing and spending.

Fiscal policy refers to how a government adjusts its spending levels and tax rates to influence a country’s economy. By altering these two components, the government can either stimulate economic growth or cool down an overheated economy. For example, increasing government spending can create jobs and boost demand, while increasing taxes can slow down spending and inflation.

The correct answer is 1. abundance of treasures that had been preserved for centuries.

Howard Carter’s discovery of King Tutankhamun’s tomb in 1922 revealed a vast array of treasures, including jewelry, furniture, and other artifacts that had remained largely untouched for over 3,000 years. This find was significant because it was one of the few royal tombs that had not been extensively robbed, allowing researchers to study the rich burial practices and artifacts of ancient Egypt in great detail.

The correct answer is:

B) hid the harmful aspects of American western expansion while emphasizing its allure.

Explanation: The phrase “romantic tales” suggests that Zane Grey’s stories focused on idealized and adventurous themes, making the Western landscape and lifestyle seem glamorous.

The correct answer is: more support for domestic companies.

Explanation: Trade agreements like NAFTA (North American Free Trade Agreement) and the EU (European Union) create a framework for countries to trade more freely, which often leads to increased competition and support for domestic industries. By reducing tariffs and other trade barriers, these agreements help domestic companies access larger markets, which can enhance their growth and competitiveness.

To answer how the agreement helps the nations involved, let’s check the relevant options:

1. It reduces barriers to trade. – Correct. By reducing tariffs and quotas, countries can trade more freely, benefiting their economies.

The correct answer is: Afghanistan and Iraq.

During George W. Bush’s presidency, the United States entered military conflicts primarily in Afghanistan and Iraq. Following the September 11, 2001 attacks, the U.S. invaded Afghanistan in October 2001 to dismantle al-Qaeda and remove the Taliban from power. In 2003, the U.S. led an invasion of Iraq, alleging that the Iraqi government possessed weapons of mass destruction and posed a threat.

The correct answer is the President.

National Security policies are primarily defined by the President as they are responsible for making executive decisions related to the country’s security. The President has the authority to respond to current events, lead diplomatic efforts, and direct military actions, thereby shaping the national security strategy. Congress plays a role by providing oversight and funding, but the President is the key figure in formulating these policies.
