Answer:
E = 2,575 eV
Explanation:
For this exercise we will use the Planck equation and the relationship of the speed of light with the frequency and wavelength
E = h f
c = λ f
Where the Planck constant has a value of 6.63 10⁻³⁴ J s
Let's replace
E = h c / λ
Let's calculate for wavelengths
λ = 4.83 10-7 m (blue)
E = 6.63 10⁻³⁴ 3 10⁸ / 4.83 10⁻⁷
E = 4.12 10-19 J
The transformation from J to eV is 1 eV = 1.6 10⁻¹⁹ J
E = 4.12 10⁻¹⁹ J (1 eV / 1.6 10⁻¹⁹ J)
E = 2,575 eV
Horn
Explanation:
Glaciers are powerful erosion forces as the occur. Erosion is the removal of products of weathering on the earth surface. Some of the feature of glacier erosion are:
- Glacial horns
- striations
- cirques
- glacial horns
- arêtes
- U-shaped valley e.t.c
Glaciers erode when they expand or slowly move during period of lower temperatures.
Glacier horns forms when glaciers eroded the sides of a peak leaving a sharp pointed structure behind.

Explanation: have a nice day
Answer:hypothesis: the plant died of lack of light,moisture,or water
Explanation:
to test my hypothesis i put a plant in a room at room temp and repeat how i grew it,and observe what went wrong. hope this helps=)
