Answer:
The scientist who used a prism to study light was Isaac Newton.
Explanation:
Newton was the first to understand what the rainbow was: he refracted the white light with a prism and decomposed it into basic colors: red, orange, yellow, green, blue and violet.
For his experiments, Newton used triangular glass prisms. The light penetrates one of the faces of the prism and is refracted to decompose in different colors, because the degree of separation varies depending on the wavelength of each color. The prisms act in this way thanks to the fact that the light changes speed when it passes from the air to the crystal of the prism.
Once the colors were separated, Newton used a second prism to refract them and to form white light again. The experiment showed that the prism did not add color to light, as many believed. Newton also passed only the red color obtained with a prism for a second prism, thus discovering that the color was not altered. It was further proof that the prism did not create colors, but only separated those that were present in the original beam of light.
In large part it can be said that our current conception of light and color born with Isaac Newton and his valuable contribution to the subject.
It hired soldiers to overthrow Ho Chi Minh.
It backed Ngo Dinh Diem as president in South Vietnam.
It backed Ho Chi Minh as president in South Vietnam.
The right answer is It backed Ngo Dinh Diem as president in South Vietnam. Let's understand how:
The Geneva Accords of 1954 divided Vietnam in half at the 17th parallel, with the communist block in the north and the south. This accord also requested for elections, within 2 years, in all Vietnam in order to reunify the country. Fearing the expansion of Communism in the world, the US was opposed to the elections. In 1956, the South Vietnamese president, supported by the US, successfully blocked the unifying elections.
The United States of America influence Vietnam’s national elections in 1956 by backing Ngo Dinh Diem as president in South Vietnam.
The United States of America influence the national elections of Vietnam in the year 1956 by backing Ngo Dinh Diem as president in South Vietnam i order to control the region of southern Vietnam so we can conclude that United States backed Ngo Dinh Diem as president in South Vietnam.

b. low tariff barriers
c. high taxes
d. excessive credit expansion
The correct answer is D) excessive credit expansion.
The factors that led to the stock market crash of 1929 was excessive credit expansion.
The US stock market crash occurred on October 29, 1929. This black Tuesday led to what is known as the Great Depression that lasted until 1939. Stocks were in excess of their real value due to excessive credit expansion and the decline of production and high unemployment. After the stock market crash, people lost their jobs, many companies closed, and banks went into bankruptcy.
European industries such as textiles, agriculture, mining, and manufacturing greatly benefited from African resources, particularly during the period of colonialism and the slave trade. European nations capitalized on Africa's abundant natural resources and enslaved populations to fuel their industrial growth and support their economies. This had significant and lasting effects on African societies and industries.
Various European industries benefited greatly from African resources, especially during the periods of colonialism and the slave trade. The most prominent industries included the textile and metal industries, agriculture, and mining. Due to Africa's rich natural resources, European nations saw the continent as a valuable prize and moved in swiftly to control it, leading to a phenomena known as the 'Scramble for Africa'.
A significant portion of the African population was enslaved and taken across the Atlantic to work on European plantations where cash crops like sugar, rice, and tobacco were grown, which were then shipped back to Europe. This played a major role in the triangular trade and had a significant impact on industries in both Africa and Europe. The influx of European goods disrupted African industries, particularly manufacturing, as they could not compete on quantity or price.
Additionally, Africa was seen as a significant source of raw materials for European factories during the industrial revolution. Notable resources included cotton, sugar, tea, and tobacco, which were cultivated using the labor of enslaved populations in New World plantations. The extensive exploitation of these resources had a profound effect on African societies and industries.
