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.

According to this map, most of the land in Brazil is used for what purpose?
schepotkina [342]

Answer:

Forest is the correct option.

Explanation:

Sixty percent of land in Brazil consist o forest and the share of Arable land is 32 percent. It is also the most bio diverse countries in the world. The bulk of the Brazilian forest lies in the Amazon Basin. But the country is witnessing the loss of forest cover in the past few years. Especially after the 1970's it has lost 19 percent of its forest cover area, due to the construction of Trans- Amazonian highway and the growing population in the Amazon basin.

Land use pattern in Brazil: 32 percent of the land is Arable Land. 60 percent is Forest Land and 5.2 percent of the land is used for other activities. Out of 32 percent of Arable land, less than one percent is used for growing permanent crops, while 23 percent is permanent pasture.
