A carbon fiber car bumper is hit by another car with the stress of 106,483 Pa. If carbon fiber has a Young's modulus of 228 x 10
hoa [83]

Answer:

Stress = 4.67 * 10^-7 N/m²

Explanation:

Young's modulus of the material = Stress/Strain

Given

Young's modulus  = 228 x 10^9 Pa

Stress =  106,483 Pa

Required

Strain

From the formula;

Strain = Stress/Young modulus

Strain =  106,483 /228 x 10^9

Stress = 4.67 * 10^-7 N/m²

1. Indica cuáles son los reactivos y productos de la reacción química representada por la ecuación siguiente, y señala en que es
bearhunter [10]

Answer:

Los reactivos, con su correspondiente estado de agregación, son:

  • Mg: estado sólido
  • HCl: estado acuoso

Los productos, con su correspondiente estado de agregación, son:

  • MgCl₂: estado acuoso
  • H₂: estado gaseoso

Explanation:

Una reacción química es un proceso por el cual una o más sustancias se transforman en otra u otras sustancias con propiedades diferentes. En otras palabras, las reacciones químicas son procesos en los que los átomos rompen sus enlaces químicos y forman otros nuevos, cambiando la naturaleza de las sustancias que intervienen.

En una ecuación química se representan dos términos. En el primero, el de la  derecha, se escriben los reactivos, expresados mediante sus fórmulas químicas  correspondientes y separados por un signo más. Por otro lado, el término de la izquierda, en  el que aparecen los productos, también representados por sus formulas químicas  correspondientes y con signos más entre ellos. Entre ambos términos suele ponerse  una flecha que indica que se ha producido la reacción química correspondiente.

Las sustancias que hay antes de producirse el cambio y que desaparecen se llaman reactivos. Las sustancias que hay después de producirse el cambio y que aparecen o se generan se llaman productos.

El estado de agregación en una reacción química se indica poniendo detrás del nombre o la fórmula de la sustancia y entre paréntesis la notación siguiente:

  • Sustancias sólidas (s)
  • Sustancias líquidas (l)
  • Sustancias gaseosas (g)
  • Sustancias disueltas en agua (aq)

En este caso tienes la reacción química:

Mg (s) + 2 HCl (aq) -> MgCl₂ (aq) + H₂ (g)

Entonces, <u><em>en este caso los reactivos, con su correspondiente estado de agregación, son:</em></u>

  • <u><em>Mg: estado sólido</em></u>
  • <u><em>HCl: estado acuoso</em></u>

<u><em>Por otro lado, los productos, con su correspondiente estado de agregación, son:</em></u>

  • <u><em>MgCl₂: estado acuoso</em></u>
  • <u><em>H₂: estado gaseoso</em></u>

If tides occur twice a day in most places. How much time is there between a morning high tide and the next high tide?
algol13

About 12 hours is the time between a morning high tide and the next high tide

Explanation:

The Earth’s rotation happens between two tidal bulges  

The “periodic rise and fall” of the surface water levels of the ocean is called tides. The gravitational action and interaction on the earth by the sun and the moon causes these tides. Different regions of the World experiences different patterns of tides like the diurnal, semi-diurnal etc.

When there is one high and one low tide occurring on a lunar day, then it is diurnal pattern. Semi-diurnal pattern occurs when there are two equal high and low tides on a single lunar day.

Since the Earth’s rotation happens between two tidal “bulges” on each lunar day, the coastal areas can experience two high and two low tides in every 24 hours plus 50 minutes.

Accordingly the time between two high tides would be 12 hours plus 25 minutes. Similarly, the time gap between a high to low tide would be 6 hours plus 12.5 minutes.
