Answer:

Energy of electrons depends on light's frequency, not intensity.

Explanation:

The photoelectric effect was discovered by physicist Henrich Hertz. Albert Einstein, in 1905, modernized the concepts of this effect when he realized that the energy of electrons depends on the frequency of light, not on intensity.

The discovery of this effect occurred between 1886 and 1887 by Henrich Hertz, who used classical physics to explain it. The classical concepts made the conception of this phenomenon insufficient, giving way to the modern concepts proposed by Albert Einstein in 1905. Among Einstein's proposals are the quantization of energy, that is, for the occurrence of immediate electron ejection from the surface, the radiation energy (electromagnetic waves) would be concentrated in packages (photons) and not distributed over the wave (classical prediction). It also demonstrated that the speed at which electrons are ejected does not depend on the amount of photons emitted, but on the frequency of these photons.

What factors led to the feeling of upheaval in the u.s in the years following world war 1

shtirl [24]

Answer: Economic reasons.

Explanation:

It was not until 1917 that the United States entered the war. During the war, the United States provided loans to the Entente forces for military, medical, and food supplies. These loans were primarily the burden of the French and the United Kingdom. In this way, the US has profited from these loans.

The problem was that the Entente could lose the war. In these circumstances, the indebted countries would not be able to repay the loan to America. Because of this fact, the United States decides to engage in war to help the anthem win and to secure its economic benefit by borrowing.

Margarita [4]

Many things could change. For starters, he could reach the new shore 10 times as faster thanks to modern ships and/or airplanes that could land even where there are no runways. He wouldn't even have to go there to find it since he could use satellites to scan the Earth and see that there's a large land mass there, instantly figure out that it's not India but rather a new continent, and he could just go there in a plane in a single day of travel or so.
