Answer:

La densidad del líquido desconocido es de aproximadamente 0,6855 g/ml.

Step-by-step explanation:

Los parámetros dados son;

La masa del recipiente vacío = 38,52 g

La masa total del recipiente cuando está lleno de agua = 137,26 g

La masa total del recipiente cuando se llena con el líquido desconocido = 106.21 g

Por lo tanto;

La masa del agua = La masa total del recipiente cuando está lleno de agua - La masa del recipiente vacío

La masa del agua = 137,26 g - 38,52 g = 98,74 g

La masa del líquido desconocido = 106,21 g - 38,52 g = 67,69 g

La gravedad específica del líquido desconocido = (La densidad de la sustancia desconocida) / (La densidad del agua)

De lo que tenemos;

La gravedad específica del líquido desconocido = (La masa del líquido desconocido) / (La masa de un volumen igual de agua)

∴ La gravedad específica del líquido desconocido = (67,69 g) / (98,74 g) ≈ 0,6855

De la ecuación, gravedad específica = (La densidad del líquido desconocido) / (La densidad del agua) y la densidad del agua = 1 g / ml, tenemos;

gravedad específica ≈ 0.6855 = (La densidad del líquido desconocido) / (1 g / ml)

La densidad del líquido desconocido ≈ 0.6855 × 1 g / ml ≈ 0.6855 g / ml

La densidad del líquido desconocido ≈ 0,6855 g / ml.

Arisa [49]
“If Brad drank all the juice in a juice box, how much juice did he drink?” would be the answer because it is the only answer reffering to finding the volume of an object (the juice box) and the volume being the amount of juice.

samantha threw an apple out of a window from the tenth floor of her appartment building. the equation y = -16t^2+120 can be used
ella [17]
Answer:
time taken = 2.74 seconds

Explanation:
We are given that:
y = -16t² + 120 models the situation where:
y is the floor number
t is the time taken for the apple to hit the ground

We are also given that the floor number (y) is 10. Therefore, all we have to do is substitute with y in the above equation and solve for the time t as follows:
y = -16t² + 120
10 = -16t² + 120
120 - 10 = 16t² 
110 = 16t²
t² = 110/16
t² = 6.875
either t = 2.74 seconds ..........> accepted
or t = -2.74 seconds .........> rejected as time cannot be in negative

Hope this helps :)
