• Al considerar 51 m como la distancia entre dos puntos situados realmente a 52.06 m • Como medida del radio de una gota de saliva de 3 µm hemos obtenido 2.97 µm.

Calcula el error absoluto y el relativo.

• Al medir 2 m se ha cometido un error de 2 mm, y en 400 Km el error cometido fue de 400 m. ¿Qué error relativo es mayor?

• La distancia entre Santiago y Santo Domingo es de 155.56 km.

a)Aproxima la distancia hasta las décimas tanto por redondeo y por truncamiento.

b)Calcula el error absoluto cometido en ambos casos.

c)Justifica, de acuerdo con los resultados anteriores, qué aproximación es mejor.

• Al medir un matraz de laboratorio con un rango de incertidumbre de ± 1 mm se obtienen como medidas de su diámetro de base 9.1 cm y de altura de 17.2 cm, determina el porcentaje de incertidumbre de cada una de estas mediciones.
