Calculate the energy of one photon of yellow light that has a wavelength of 5.89x10^-7m.​
Viktor [21]

Answer:

E = energy = ? ,

λ = Wavelength = 5.89 × 10^-7 m —> = 589 ×10 ^-9 m ,

h =Planck constant = 6.63 × 10^-34 J.s ,

f = frequency of photo/ electromagnetic radiation = c/λ ,

c = Speed of light in a vacuum = 3 × 10^8 m/s

___o___o____

E = hf \\  \\ E = h \frac{c}{λ}  \\  \\  E = 6.63 \times  {10}^{ - 34}  \frac{3 \times  {10}^{8} }{5.89 \times  {10}^{ - 7} }  \\  \\E =  \frac{6.63 \times  {10}^{ - 34} \times 3 \times  {10}^{8}  }{5.89 \times  {10}^{ - 7} }   \\  \\ E =  \frac{663 \times  {10}^{ - 36} \times 3 \times  {10}^{8}  }{589 \times  {10}^{ - 9} }  \\  \\ E =  \frac{1989 \times  {10}^{ - 28} }{589 \times  {10}^{ - 9} }  \\  \\ E = 3.37691 \times  {10}^{ - 19} J

Las capas del lecho marino del Mar Mediterráneo cuentan la historia de los cambios ambientales en el hoy desértico norte de Afri
slamgirl [31]

Answer:

160.000 años corresponde a 16.000 décadas.

Explanation:

Para resolver correctamente el ejercicio debemos plantear la regla de tres simple de la siguiente manera:

1 década equivale a 10 años; A cuantas decadas equivalen 160.000 años?

1 década→10 años

          x    ←160.000 años

Debemos multiplicar 160.000 por 1 y luego dividir entre 10 ;

x=(\frac{160.000x1}{10})=16.000 décadas; en notación científica sería 16x10^3.

Respuesta: 160.000 años corresponde a 16.000 décadas.

A large sample of solid calcium is crushed into smaller pieces for testing. Which two physical properties are the same for both
jarptica [38.1K]
Lets go over what our properties are

-Mass is a measure of the amount of matter available. 
<span>
-Density is the ratio of mass to volume. Density is determined to be a physical object</span>

<span>-Volume is the amount of space occupied by the object. </span>

<span>-Solubility is the amount of a substance required to form a saturated solution with a specific amount of solvent at a specified temperature. 
</span>
-Mass is the same size and weight of an object for the most part which cannot be the same for a bigger or smaller object. Which means density cannot either since density has a direct correlation with mass. Volume is usually the size occupied at the current time. This means it cannot be the same for a large and small object. Note that! Then we have solubility which is the amount required or needed but since you are just crushing the solid it would wind up still being the same amount.

-With this all put together we can say your answer is probably Solubility and Desnity.
