Answer:
<u><em>It happened in 1607.</em></u>
Explanation:
<u><em>The first colony was established at Jamestown, Virginia, in 1607.</em></u> A lot of people settled in the New World escaping religious persecution. The Pilgrims arrived in 1620. and founded Plymouth, Massachusetts. In both Virginia and Massachusetts, the colonists had some kind of, we could say <em>support</em> from Native Americans.
European Nations established colonies in North America because they wanted to expand their horizons (main reasons were the<em> gold, glory</em>, and <em>spreading their religion</em>). They also wanted to have <em>more land</em> than other countries.
The Spanish were among the first Europeans to explore the New World and the first to settle in what is now the United States.
By 1650, England had established a dominant presence on the Atlantic coast. They discovered <em>corn</em> which kept them from starving while, in Virginia, <em>tobacco</em> was a great way to make money. In early 1700s enslaved Africans contributed a growing percentage of the colonial population. By 1770, more than 2.000.000 people lived and worked in Great Britain's 13 North American colonies.
Answer:
Visible light range (between 400 and 800 nm).
Explanation:
The Sun emits a large range of electromagnetic waves, from gamma rays (higher frequencies) to radio waves (lower frequencies), through X-rays, ultraviolet rays, visible light, infrared radiation, microwaves. The peak of the Sun's energy output is actually in the visible light range (between 400 and 800 nm).
In the graph I annexed, you can see a simplified representation of the energy emissions of the Sun versus the wavelengths of those emissions. The y-axis shows the amount of energy emitted at a given wavelength and the x-axis represents different wavelengths of EM radiation. In this graph is observable than the major emission of radiation emitted by the Sun is in the visible range.
