Respuesta:

60°

Explicación:

Paso 1: Información dada

  • Distancia recorrida (d): 2000 cm
  • Fuerza aplicada (F): 80 N
  • Trabajo realizado (W): 800 J

Paso 2: Convertir "d" a metros

Usaremos el factor de conversión 1 m = 100 cm.

2000 cm × 1 m/100 cm = 20 m

Paso 3: Calcular el ángulo entre la cuerda y el suelo (θ)

W = F × d × cosθ

800 J = 80 N × 20 m × cosθ

θ = 60°

Consider a reaction that has a positive ΔH and a positive ΔS. Which of the following statements is TRUE?A) This reaction will be
Alja [10]

Answer: A) This reaction will be spontaneous only at high temperatures

Explanation:

\Delta G= +ve, reaction is non spontaneous

\Delta G= -ve, reaction is spontaneous

\Delta G= 0, reaction is in equilibrium

Using Gibbs Helmholtz equation:

\Delta G=\Delta H-T\Delta S

Given : \Delta H=+ve

\Delta S=+ve

\Delta G=(+ve)-T(+ve)

\Delta G=(+ve)(-ve)

Thus the value of  \Delta G  is negative and spontaneous when temperature is high.
