Answer:

Technically, humans are causing global warming.

Explanation:

There's some research done into this (sadly not enough), some of which can be found here, https://www.nationalgeographic.com/environment/global-warming/global-warming-causes/ and here, https://climate.nasa.gov/causes/ . The basics are as follows: Earth is a greenhouse. Sunlight comes towards us, and while some is reflected out, most is absorbed through greenhouse gasses, like Carbon Dioxide. Because of humanity, the amount of carbon dioxide in the air has increased, leading to more warmth from the sun to be absorbed. Therefore, the earth is getting warmer because of us.

Define the Element of Art, value. If you were using a pencil, how would you create a darker value?
ankoles [38]

Elements of art are stylistic features that are included within an art piece to help the artist communicate. The seven most common elements include line, shape, texture, form, space, colour and value, with the additions of mark making, and materiality.

You would create a darker value if you shaded it, shading it makes it darker.

An electron in the n = 5 level of an h atom emits a photon of wavelength 1282.17 nm. to what energy level does the electron move
lions [1.4K]
This is an interesting (read tricky!) variation of Rydberg Eqn calculation.
Rydberg Eqn: 1/λ = R [1/n1^2 - 1/n2^2]
Where λ is the wavelength of the light; 1282.17 nm = 1282.17×10^-9 m
R is the Rydberg constant: R = 1.09737×10^7 m-1
n2 = 5 (emission)
Hence 1/(1282.17 ×10^-9) = 1.09737× 10^7 [1/n1^2 – 1/25^2]
Some rearranging and collecting up terms:
1 = (1282.17 ×10^-9) (1.09737× 10^7)[1/n2 -1/25]
1= 14.07[1/n^2 – 1/25]
1 =14.07/n^2 – (14.07/25)
14.07n^2 = 1 + 0.5628
n = √(14.07/1.5628) = 3
