The time it takes for half of the atoms in an isotope to decay is called

Answers

Answer 1

Answer:

When atom decays, two or more forms of the same element are obtained. These forms are called isotopes and they have the same number of protons but a different number of neutrons in relation to the parent atom. So they differ in the relative atomic mass, which is the number of core particles, while the chemical properties remain the same as the parent atom. This process takes place with radioactive decays where radioactive isotopes are obtained, and the time required for decay is half life, and this is the time that is needed for half atom parent to decay and form the daughter elements.

Answer 2

Answer: I think the answer would be Half-Life

1.Do you think President Ronald Reagan's policies had a positive or negative effect on the country overall? Explain your response.2.What do you think was the most significant event of the 1980s and why?

Answers

President Ronald Reagan's policies had a positive effect on the country overall. He had a plan for the country's economy that included cutting taxes, deregulation, and reducing the size of government. Because of his policies, he was able to be re-elected and help America improve further.

Answer:

1- Reagan's policies had a positive effect on the United States.

2- The most significant event of the 1980s was the fall of the Berlin Wall.

Explanation:

1- Reagan's presidency had positive effects for the United States. Reagan ended decades of a cycle of debilitating tax levels and an excess of dependence on state control over the economy. Its policies allowed an explosion of economic growth.

There was much at stake, as much as in his international politics where Reagan contributed decisively to defeat Communism and opened the door for the reunification of Europe.

Reagan's arguments about the negative effects of high tax rates, the risks of a government in constant growth and the meaning of fiscal deficits, are still key in the debate on economic policy.

By achieving a huge tax cut during his first year in office, Reagan changed the tax policy of America in such a profound way that even today his followers are thrown into politics with platforms that use variations of his plan. After his tax cuts, several years of economic expansion came, but at the same time government debt tripled, a legacy that his critics always remember.

But his most lasting economic legacy is actually in another aspect: complementing the intellectual foundations established by Nobel laureate economist Milton Friedman, as well as the political impetus of British Prime Minister Margaret Thatcher, Reagan helped to divert the global economy from controls of the government and helped steer it towards the deep and lasting forces of the market.

There is little doubt in the world that this part of his legacy lives on. In many parts of the world where state control of the economy was seen as the salvation of the poor, stock markets are now developing and new entrepreneurs are born.

Reagan's ideas were not limited to the economic sphere, by the way. The former president left a mark so deep that Reaganism continues defining the American political positions in subjects that go from policy and defense until economy.

He told the country in the 70s that America was prepared to have a conservative president. Although his prediction took a bit longer to be fulfilled, it was accurate. Reagan went to Berlin and told the Soviets to destroy the Berlin Wall. Less than three years later, the wall fell. And he said that communism was going to be history and, again, he was not wrong.

2- The fall of the Berlin Wall on November 9, 1989 represented the German unification, the fall of Soviet influence in this country and the beginning of the end of communism in Eastern Europe. Virtually, it was the first step on the road to the disintegration of the Soviet Union two years later. Therefore, without a doubt it was the most important event of the 1980s.

Big business shaped the American economy in the late 1800s and early 1900s by outproducing smaller "family business," which drove prices down. This happened in large part due to the Industrial Revolution.
