Introduces una masa de 80g en una probeta con 60cm cúbicos de agua y el nivel sube hasta 75cm cúbicos. qué densidad tiene la mas
ExtremeBDS [4]

Answer:

d=5.33\ gr/cm^3

Explanation:

<u>Densidad</u>

La densidad de una masa m que ocupa un volumen v se define como:

\displaystyle d=\frac{m}{V}

Tenemos que una masa de 80 gr hace que un volumen de agua se desplace desde 60 cm3 hasta 75 cm3, es decir, el volumen propio de la masa es m = 75 - 60 = 15 cm3.

Con esta información se calcula la densidad:

\displaystyle d=\frac{80\ gr}{15\ cm^3}

Operando:

\boxed{d=5.33\ gr/cm^3}

What are two reasons the period of Venus is shorter than the period of earth
Setler79 [48]

Answer: The planet, named after the Roman goddess of art and beauty, can actually be bright enough to cast shadows on a moonless night. It appears so close to the sun because its orbital radius is smaller than the Earth's, and because it also moves faster than Earth, its orbital period is shorter.
