Answer:
La oscuridad de una mancha solar es solamente un efecto de contraste; si pudiéramos ver una mancha tipo, con una umbra del tamaño de la Tierra, aislada y a la misma distancia que el Sol, brillaría unas 50 veces más que la Luna llena. Las manchas están relativamente inmóviles con respecto a la fotosfera y participan de la rotación solar. El área de la superficie solar cubierta por las manchas se mide en términos de millonésimas de hemisferio solar visible.

Answer: (x+7)(x-7)
how to get answer:
x^2-49 rewrite as
x^2-7^2
use diff of perf squares: a^2-b^2=(a+b)(a-b)
(a=x, b=7)
fill in the formula of the parenthesis
(x+7)(x-7)
to check you answer is correct, you can foil the answer (x+7)(x-7)
Answer:
With the development of industry (finally followed by the accelerated connection of settlements), more and more emissions of various gases into the atmosphere began.
Explanation:
Gases, ie particles on which the solar radiation (at least its infrared part) is efficiently dissipated and according to a larger published mechanism additionally warms the planet.
A large number of other gases, such as carbon monoxide and methane, are also taking up more and more space in the air, thus increasing the warming effect of the planet.
These gases do not only destroy the atmosphere directly. Between 30% and 40% of carbon dioxide (and the percentage of others) dissolves in the oceans. This mechanism reduces the pH value of water or increases the acidity.
