What determines the brightness of a light wave?

Chemistry
1 answer:
Reptile [31]3 years ago
5 0

Answer: The brightness of light is related to intensity or the amount of light an object emits or reflects. Brightness depends on light wave amplitude, the height of light waves. Brightness is also somewhat influenced by wavelength.

Si un hombre realiza una fuerza horizontal de 13 Kgf sobre una pared, y ésta no se mueve. ¿Cuánto suman las fuerzas realizadas p
aliya0001 [1]

Answer:

La fuerza resultante o de reacción por parte de la pared es igual a cero

Explanation:

Aunque se aplique una fuerza de 13 kgf sobre la pared ,esta fuerza no es lo suficiente para que se mueva por lo tanto la pared o el objeto al que se le aplica la fuerza está en equilibrio estático.

El que el objeto o la pared esté en equilibrio estático quiere decir que la resultante de las fuerzas que actúan sobre el objeto es cero.

A 3.5 gram sample of a radioactive element was formed in a 1960 explosion of an atomic bomb at Johnson Island in the Pacific tes
Annette [7]
The answer is 0.62g.
Solution:
From year 1960 to year 2030, it has been 
     2030-1960 = 70 years

The half-life of the radioactive element is 28 years, then the sample will go through
     70 years * (1 half-life/28 years) = 2.5 half-lives

Starting with a 3.5 gram sample, we will have
     3.5*(1/2) after one half-life passes
     3.5*(1/2) * (1/2) = 3.5*(1/4) after two half-lives pass
     3.5*(1/4) * (1/2) = 3.5*(1/8) after three half-lives pass and so on

Therefore, we can write the remaining amount of the sample after the number n of half-lives have passed as
     mass of sample = initial mass of sample/2^n

The mass of the remaining sample for n = 2.5half-lives can be now calculated as
     mass of sample = 3.5 grams / 2^2.5 = 0.62 g

Consider that a sample of a compound is decomposed and the masses of its constituent elements is as follows: 1.443 g Se, 0.5848
sladkih [1.3K]

Answer: The empirical formula is SeO_2.

Explanation:

So, the mass of each element is given:

Mass of Se = 1.443 g

Mass of O = 0.5848 g

Step 1 : convert given masses into moles.

Moles of Se=\frac{\text{ given mass of Se}}{\text{ molar mass of Se}}= \frac{1.443g}{79g/mole}=0.018moles

Moles of O = \frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{0.5848g}{16g/mole}=0.036moles

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For Se = \frac{0.018}{0.018}=1

For O =\frac{0.036}{0.018}=2

The ratio of Se: O = 1: 2

Hence the empirical formula is SeO_2.
