Anyone know this ??
Nady [450]

Answer: The first one does not belong, neither does the third.

Step-by-step explanation:

The second one belongs as 30+5=35. You can divide 35 by 5 to get A=7. This is a valid answer. The third is the same as the first. The fourth acts for 30+25=5. 55/5=11.A=11. This is also a valid answer. So, the first one does not belong and neither does the third.

.Un recipiente cilíndrico de 5cm de radio y 10cm de altura se llena de agua. Si la masa del recipiente lleno es de 2kg, ¿cuál es
Lera25 [3.4K]

Answer:

La masa del recipiente vacío es 1,2146 kg.

Step-by-step explanation:

La densidad se define como la propiedad que tiene la materia, ya sean sólidos, líquidos o gases, para comprimirse en un espacio determinado. En otras palabras, la densidad es una magnitud que permite medir la cantidad de masa que hay en determinado volumen de una sustancia. Entonces, la expresión para el cálculo de la densidad es el cociente entre la masa de un cuerpo y el volumen que ocupa:

densidad= \frac{masa}{volumen}

Entonces la masa puede ser expresada como:

masa= densidad*volumen

En este caso:

  • densidad del agua= 1000 \frac{kg}{m^{3} }
  • volumen del recipiente cilíndrico= π*radio²*altura= π*(5 cm)²* 10 cm= π*(0,05 m)²*0,1 m= 7,854*10⁻⁴ m³

Reemplazando:

masa= 1000 \frac{kg}{m^{3} } * 7,854*10⁻⁴ m³

masa=0.7854 kg

Si la masa del recipiente lleno es de 2 kg, entonces se le resta la masa de agua calculada:

2 kg - 0,7854 kg= 1,2146 kg

Entonces,<u><em> la masa del recipiente vacío es 1,2146 kg.</em></u>

<u><em> </em></u>

<u><em></em></u>
