Answer: B. Can provide humans with energy forever

Explanation:  The warm air rises and cooler air rushes in to take its place. The moving air is wind. As long as the sun shines, there will be winds on the Earth. We will never run out of wind energy.

Newton’s second law of motion
Fiesta28 [93]

When an object of mass 2Kg and applied force is 10N then acceleration is 5 m/s/s.

<h3>What is Newton's second Law?</h3>

Newton's second Law of motion will be represented as:

F = m.a, where

  • F = force
  • m = mass of object
  • a = acceleration

Acceleration for the first row will be calculated as:

  • a = 10/2 = 5 m/s/s

Acceleration for the second row will be calculated as:

  • a = 40/5 = 8 m/s/s

Mass for the third row will be calculated as:

  • m = 20/5 = 4kg

Mass for the forth row will be calculated as:

  • m = 45/45 = 1 kg

Force for the fifth row will be calculated as:

  • F = (3)(3) = 9 N

Hence, acceleration of the object whose mass is 2kg and force on that object is 10N is 5m/s/s.

El volumen de un gas en un recipiente cerrado es de 3.5 litros a una temperatura de 25oC y una atmósfera constante de presión. ¿
polet [3.4K]

Answer:

El volumen del gas en el recipiente es 3.29 L si se disminuye la temperatura a 7°C

Explanation:

La Ley de Charles es una ley de los gases que relaciona el volumen y la temperatura de una cierta cantidad de gas a presión constante.

Esta ley establece que el volumen es directamente proporcional a la temperatura del gas. Es decir que si la temperatura aumenta, el volumen del gas aumenta, mientras que si la temperatura del gas disminuye, el volumen disminuye.

Matemáticamente, si la cantidad de gas y la presión permanecen constantes, el cociente entre el volumen y la temperatura siempre tiene el mismo valor:

\frac{V}{T}=k

Suponiendo un cierto volumen de gas V1 que se encuentra a una temperatura T1 al comienzo del experimento, al variar el volumen de gas hasta un nuevo valor V2, entonces la temperatura cambiará a T2, y se cumplirá:

\frac{V1}{T1}=\frac{V2}{T2}

En este caso, sabes:

  • V1= 3.5 L
  • T1= 25 °C=298 °K (siendo 0°C=273°K)
  • V2=?
  • T2=7 °C=280 °K

Reemplazando:

\frac{3.5 L}{298 K}=\frac{V2}{280 K}

Y resolviendo obtienes:

V2=280 K*\frac{3.5 L}{298 K}

V2= 3.29 L

<u><em>El volumen del gas en el recipiente es 3.29 L si se disminuye la temperatura a 7°C</em></u>
