5 0

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°

Explain what makes insulative materials work most effectively.
KengaRu [80]

Answer:

Most common insulation materials work by slowing conductive heat flow and--to a lesser extent--convective heat flow. Radiant barriers and reflective insulation systems work by reducing radiant heat gain. To be effective, the reflective surface must face an air space.

Explanation:

To be effective, the reflective surface must face an air space.

Please tell me an example of a protein structure that would give positive test with Molisch’s Reagent?
Andru [333]

Answer:

positive reaction for Molisch's test is given by almost all carbohydrates (exceptions include tetroses & trioses). It can be noted that even some glycoproteins and nucleic acids give positive results for this test (since they tend to undergo hydrolysis when exposed to strong mineral acids and form monosaccharides).
