Answer:

Infer.

Explanation:

Hello,

In this case, when we conclude through reasoning from something known or assumed is to infer, as we all make inferences which come from conclusions by using information we have to obtain new information. When we infer, we connect the facts from the known to the unknown, from the stated to the unstated. To infer turns out into a logical conclusion based on an analysis of stuffs, circumstances, situations, facts, and conceptions that seem reliable in light of what is known.

Best regards.

The mass of the quartz crystal shown below is 10 grams, and its volume is 4 cm3. What is the density of quartz?
Tju [1.3M]

Answer:

{\boxed{\text{b. 2.5 g/cm}^{3}}}

Explanation:

\text{Density} = \dfrac{m}{V} = \dfrac{\text{mass}}{\text{volume}}

Data:

m = 10 g

V = 4 cm³

Calculation:

\text{Density} = \dfrac{\text{10 g}}{\text{4 cm}^{3}} = \textbf{2.5 g/cm}^{3}\\\text{The density of the crystal is ${\boxed{\textbf{2.5 g/cm}^{3}}}$}

Una piedra es lanzada horizontalmente desde la azote de un edificio de 30 metros de altura, con una velocidad de 12 m/s. Hallar
drek231 [11]

Answer: La piedra tarda 2.47 segundos en caer al suelo, y cae a 29.64 metros de la base del edificio.

Explanation:

Ok, tenemos 2 sistemas de ecuaciones para este problema.

Primero, el vertical:

La aceleración es la aceleración gravitatoria, entonces:

a = -9.8m/s^2

para la velocidad podemos integrar sobre el tiempo y obtenemos

v = (-9.8m/s^2)*t + v0

donde v0 es la velocidad inicial, pero la velocidad inicial es solo horizontal, entonces v0 = 0.

Para la posición integramos de vuelta:

p = (1/2)*(-9.8m/s^2)*t^2 + p0

donde p0 es la posición inicial, en este caso, 30m

p = (-4.9m/s^2)*t^2 + 30m

la piedra va a llegar al piso cuando la posición vertical sea igual a 0m

p = 0m =  (-4.9m/s^2)*t^2 + 30m

de aca podemos despejar el tiempo que la piedra tarda en llegar al suelo.

t = √(30/4.9) segundos = 2.47 s.

Ahora, las ecuaciones para el movimiento horizontal son:

Aceleración nula, pues no hay ninguna fuerza actuando en la dirección horizontal.

a = 0

para la velocidad, integramos sobre el tiempo:

v = 0*t + v0 = v0

donde v0 es la velocidad inicial, en este caso, es 12m/s

v = 12m/s

para la posición integramos de vuelta:

p = 12m/s*t + p0

en este caso podemos asumir que estamos inicialmente en el punto x = x0, asi que la posición inicial es p0 = x0.

p = 12m/s*t + x0

entonces, si queremos calcular la distancia entre la base del edificio y el punto donde cae la piedra, tenemos que calcular:

D = p(2.47s) - p(0s)

D = 12m/s*2.47s + x0 - (12m/s*0s + x0)

D = 29.64m

La piedra tarda 2.47 segundos en caer al suelo, y cae a 29.64 metros de la base del edificio.
