In each cycle of its operation or refrigerator removes 17 J of heat from the inside of the refrigerator and releases 40 J of hea
Lubov Fominskaja [6]

Answer:

23 J

Explanation:

According to the law of conservation of energy, the total heat given off to the surroundings by a refrigerator is equal to the work done by the refrigerator and the heat removed from the inside of the refrigerator.

So we can write:

Q_{h} = W+Q_{c}

where

Q_{c} is the heat removed from the cold reservoir (the inside of the refrigerator)

W is the work  done

Q_{h} is the work released into the hot reservoir (the surroundings)

Here we have:

Q_c=+17 J (heat removed from the inside of the refrigerator)

Q_h=+40 J (heat released into the surroundings)

Solving the equation for W, we find the work done:

W=Q_h-Q_c=40-17=23 J

Un automóvil viaja a la velocidad de 10 m/s. Se acelera Durante 12s y aumenta su velocidad hasta 70 m/s ¿Que aceleración experim
VladimirAG [237]

Answer:

Aceleracion = 5 m/s²

Explanation:

Dados los siguientes datos;

Velocidad inicial = 10 m/s

Velocidad final = 70 m/s

Tiempo, t = 12 segundos

Para encontrar la aceleración;

Aceleración se puede definir como la tasa de cambio de la velocidad de un objeto con respecto al tiempo.

Esto simplemente significa que la aceleración viene dada por la resta de la velocidad inicial de la velocidad final a lo largo del tiempo.

Por lo tanto, si restamos la velocidad inicial de la velocidad final y la dividimos por el tiempo, podemos calcular la aceleración de un objeto. Matemáticamente, la aceleración viene dada por la fórmula;

Aceleracion = \frac{final \; velocidad  -  inicial \; velocidad}{tiempo}

Sustituyendo en la fórmula, tenemos;

Aceleracion = \frac{70 - 10}{12}

Aceleracion = \frac{60}{12}

Aceleracion = 5 m/s²
