Answer:
194,22g/mol
Explanation:
8*12,01+10*1,01+4*14,01+2*16=194,22g/mol
Answer:
D) 8.0 s.
Explanation:
(The following exercise is written in Spanish. Hence, explanations will be held in such language.)
La energía requerida para elevar el ascensor es el cambio en la energía potencial gravitacional, cuya magnitud es:
![\Delta E_{g} = (200\,kg)\cdot \left(9.807\,\frac{m}{s^{2}} \right)\cdot (20\,m)](https://tex.z-dn.net/?f=%5CDelta%20E_%7Bg%7D%20%3D%20%28200%5C%2Ckg%29%5Ccdot%20%5Cleft%289.807%5C%2C%5Cfrac%7Bm%7D%7Bs%5E%7B2%7D%7D%20%5Cright%29%5Ccdot%20%2820%5C%2Cm%29)
![\Delta E_{g} = 39228\,J](https://tex.z-dn.net/?f=%5CDelta%20E_%7Bg%7D%20%3D%2039228%5C%2CJ)
Ahora, la potencia media es el resultado anterior dividido por el tiempo. Se despeja el tiempo de la ecuación:
![\Delta t = \frac{\Delta E_{g}}{\dot W}](https://tex.z-dn.net/?f=%5CDelta%20t%20%3D%20%5Cfrac%7B%5CDelta%20E_%7Bg%7D%7D%7B%5Cdot%20W%7D)
![\Delta t = \frac{39228\,J}{5000\,W}](https://tex.z-dn.net/?f=%5CDelta%20t%20%3D%20%5Cfrac%7B39228%5C%2CJ%7D%7B5000%5C%2CW%7D)
![\Delta t = 7.846\,s](https://tex.z-dn.net/?f=%5CDelta%20t%20%3D%207.846%5C%2Cs)
La opción más aproximada es D.

Answer:
Friction
Explanation:
Brief elaboration, Friction is a force that opposes motion. When two objects are in contact, friction is acts in a direction opposite to the motion of the object.
In a spectrograph, black lines can be seen going through the array of colors. The pattern of these lines indicate the composition of the star.
Different elements block different parts of the spectrum, resulting in black lines.
