Durante 50 s un cuerpo viaja a una velocidad de 18.5 m/s, ¿Qué distancia recorrió?
weeeeeb [17]

Answer:

Distancia = 925 metros.

Explanation:

Dados los siguientes datos;

Tiempo = 50 segundos

Velocidad = 18.5 m/s

Para encontrar la distancia recorrida;

Matemáticamente, la distancia viene dada por la fórmula;

Distancia = velocidad * tiempo

Sustituyendo en la fórmula, tenemos;

Distancia = 18.5 * 50

Distancia = 925 m.

Por tanto, el cuerpo recorrió una distancia de 925 metros.

1. Suppose during volleyball practice, you lost 2.0 lbs of water due to sweating. If all of this
Lynna [10]

Answer:

E=2052.8 kJ

Explanation:

The energy absorbed by the water is the energy it requires to evaporate. So:

Heat of .vap= 40.65 kJ/mol

The moles of water:

n_w=m_w *\frac{1000g}{2.2lbs}*\frac{1}{M}

M is the water molecular weight

n_w=2 lbs *\frac{1000g}{2.2lbs}*\frac{1}{18g/mol}

n_w=50.5mol

The energy absorbed:

E=n_w*Heat of vap.=50.5mol *40.65 kJ/mol

E=2052.8 kJ

During this reaction, P4 + 5O2 → P4O10, 1.5 moles of product were made in seconds. What is the rate of reaction? 0.011 g/min 210
Ivanshal [37]

The answer is: the rate of reaction is 850 g/min.

n(P₄O₁₀) = 1.5 mol; amount of product.

M(P₄O₁₀) = 283.9 g/mol; molar mass of phosphorus(V) oxide.

m(P₄O₁₀) = n(P₄O₁₀) · M(P₄O₁₀).

m(P₄O₁₀) = 1.5 mol · 283.9 g/mol.

m(P₄O₁₀) = 425.85 g in 30 seconds.

Make proportion: 425 g : 30 s = m(P₄O₁₀) : 60 s.

m(P₄O₁₀) = 850 g in 60 s.
