why do you think the pressure changed as it did when the temperature was increased?
Answer:
La Convención Marco de las Naciones Unidas sobre el Cambio Climático (CMNUCC) en su Artículo 1, lo define como ‘un cambio de clima atribuido directa o indirectamente a la actividad humana que altera la composición de la atmósfera mundial y que se suma a la variabilidad natural del clima observada durante períodos de tiempo comparables’. La CMNUCC distingue entre ‘cambio climático’ atribuido a actividades humanas que alteran la composición atmosférica y ‘variabilidad climática’ atribuida a causas naturales.
Los científicos han encontrado evidencias de que el clima en el planeta está cambiando a un ritmo más acelerado de lo esperado y que nuestras actividades ligadas a la producción, extracción, asentamiento y consumo, son la principal causa de este aceleramiento en el cambio.
El mayor problema de un cambio acelerado en el clima es que nuestras sociedades no están preparadas para asumir los cambios que esto nos pueda traer: derretimiento de las masas glaciares y nevados que abastecen acueductos, cambios en los ciclos de floración y fructificación de las plantas de cultivo, ascensos en el nivel de los mares donde hay mucha población viviendo, mayor ocurrencia y fuerza en lluvias, sequías, huracanes, heladas y granizadas en áreas urbanas y rurales, entre otros fenómenos que sin duda reducen nuestra calidad de vida.

What is the frequency of a wave with a velocity of 100 m/s and a wavelength
of 20 m?
A. 5 Hz
O B. 120 Hz
C. 2000 Hz
O D. 0.2 Hz
Answer:
Frequency = Velocity / Wavelength = 100 m/s / 20 m = 5 s-1 or 5 Hz.
Explanation:
The frequency of a wave with a velocity of 100 m/s and a wavelength of 20m is 5 Hz.
So, option A is correct one.
What is frequency?The number of waves that pass per unit time is called frequency.Formula: [tex]v = c/lamda[/tex]v = Frequency of wave
c = Velocity
lamda = wavelength of wave
Calculation,
Let velocity = 100 m/s
wavelength = 20m is 5 Hz.
Then, Formula: [tex]v = c/lamda[/tex]
[tex]v[/tex] = 100 m/s / 20m = 5 [tex]s^{-1}[/tex] = 5 Hz ( 1 [tex]s^{-1}[/tex] = Hz )
So, frequency of wave is 5 Hz

what are greenhouse effect 1 paragraph and come friends
pls hurry
Answer:
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.
Explanation:
Greenhouse gases are certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) that trap energy from the sun. Without these gases, heat would escape back into space and Earth's average temperature would be about 60º F colder.
the warming of the Earth's atmosphere that is caused by air pollution. Note: The greenhouse effect occurs when warmth from the sun is trapped in the Earth's atmosphere by a layer of gases (such as carbon dioxide) and water vapor.
which formation is a result of a hotspot
Answer:
Hotspots occur when one of the Earth's plates moves over an unusually hot part of the Earth's mantle. These hot areas are usually relatively stationary and result in large amounts of magma rising up, piercing a hole in the plate to form a volcano. As the plates move, a series of volcanoes can form.

Shown in the table below are solubility data for different salts in water at 60oC.
Which salt is most soluble at 60o C?
A, B, C, or D.
(Chart Below:)
Answer:
D is the most soluble in water at 60 degrees Celsius
According to the data given in the table, the salt is most soluble at 60o C - salt D.
In the given table it is given that all the salts are soluble in different concentrations in different concentrations of the water at the same temperature of 60 degrees celsius.
Salt A - 10/ 50 grams H₂OSalt B - 20/60 grams H₂OSalt C - 30/120 grams H₂OSalt D - 40/120 grams H₂OConverting them in the same amount of H₂O that is 100 grams in the same ratio:
Salt A - 10/ 50 = x/100 gram = 20 gram/ 100 gram H₂OSalt B - 20/60 = x/100 grams = 33.3 gram/ 100 gram H₂OSalt C - 30/120 = x/100 grams = 25 gram/ 100 gram H₂OSalt D - 40/120 = x/100 grams = 50 gram/ 100 gram H₂OThus, the salt D is the most soluble that is 50 grams per 100 gram H₂O.
