Answer:
Explanation:
What happens when the magnitude of one charge is doubled?
If the magnitude of one charge is doubled then the magnitude of the force is also doubled. The force is not proportional to the square of the charge, so the magnitude of the force will not change by a factor of four.
Answer:
Cuando estas especies se dividen en pequeños grupos el contacto entre ellas disminuye o se interrumpe, y se favorece entonces la endogamia y la consecuente pérdida de diversidad genética, base de la diversidad biológica y condición que otorga más chances de adaptarse a los cambios en el ambiente.
Explanation:
“Entre las facto,,res que pueden influir en la dispersión de un determinado grupo pueden encontrarse intervenciones del hombre, como la construcción de una ruta, o algunas propias de la naturaleza, como un río, que en el caso particular del animal que estoy estudiando pueden llegar a ser muy limitantes”, agrega el becario.,
Answer:
the answer is iraq dat the answer
Answer:
D) the steady, clocklike decay of certain radioactive isotopes over time.
Explanation:
Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks.
For example, when rocks are formed, such as igneous rocks (formed when molten rocks cools), certain radioactive atoms are trapped inside the rocks during this formation process. Then these radioactive atoms decay over time.
The age of the rock can be estimated by comparing the occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.
From the options;
A) this is about the formation of the radioactive molecules and not about radiometric dating
B) this is radiocarbon dating (cabon dating/carbon-14 dating)
C) the <em>assumption </em>is wrong since the radioactive isotopes decays not accumulate.
D) the corect option as I explained earlier.
Answer:
3 years
Explanation:
Even there was a dry year in 1979, the area received almost the normal amount of rain in 1980.
In 1981 however, the year was quite dry, with rainfalls in drop of almost 20%, that began one of the most important drought in the history of Brazil.
In 1982, rainfalls were down by 30% and it got even worse.
In 1983, the rainfalls were down by about 35%, essentially destroying all the agriculture system that had been severely damaged by the two previous years.
In 1984, rain came back a bit higher than its traditional levels, and in 1985, the area was flooded by rain surpassing the average by 60%!
