Answer:
Explanation:Puesto que la energía causante de la aceleración del espacio-tiempo no ha podido ser observada en forma directa, se ha dado en llamarla energía oscura. Dos candidatos teóricos que podrían hacer las veces de esta energía son una constante cosmológica no igual a cero (que pudo haber causado la inflación cósmica) y una energía repulsiva más general llamada quintaesencia.
None of the given options are correct, and the correct answer is 174 K.
<u>Explanation:</u>
Mass of N = 41.6 g
Moles = 
= 
= 1.5 moles
Pressure, P = 815 mm Hg = 1.07 atm
Volume, V = 20 L
R = gas constant = 0.08205 L atm mol⁻¹ K⁻¹
Temperature, T = ? K
We have to use the ideal gas equation,
PV = nRT
by rearranging the equation, so that the equation becomes,
T = 
Plugin the above values, we will get,
T = 
= 174 K
So the temperature of the nitrogen gas is 174 K.
Answer:
Wavelength refers to the length of a wave from one peak to the next. The amplitude or height of a wave is measured from the peak to the trough. The wavelength is measured from peak to peak. Wavelength is directly related to the frequency of a given wave form.
Answer:
As nouns the difference between impression and imprint
is that impression is the indentation or depression made by the pressure of one object on or into another while imprint is an impression; the mark left behind by printing something.
