The correct answer is D. A solid has a high to very high melting point, great hardness , and poor electrical conduction, this is a covalent network solid. This is because of the large amount of energy required to break these bonds, the said properties are exhibited by these solids.

Ann [662]

You should keep the cough drop whole. This maintains the largest surface-to-volume ratio and slows the dissolution of the cough drop.

<h3>Delay of drug action</h3>

The action of the drug can be delayed to either reduce adverse effect if the drugs to the body or to enhance its therapeutic purposes.

Because the throat is dry, the therapeutic purposes of the cough drop would only be achieved if it's dissolution is delayed in the mouth.

To do so, the cough drop should be kept whole to maintain the largest surface-to-volume ratio. This would slow the dissolution of the cough drop.

skid marks about 6.7 km long. If the car had an initial speed of 425 km/h, estimate the coefficient of kinetic friction. The acc
Zanzabum

Answer:

Explanation: F=umg where u is coefficient of kinetic friction.

But F=ma.

a = u^2/2S

U= 425km/hr = (425*1000)/3600 =118m/s

S= 6.7km = 6700m

a = 118*118/ (2*6700) = 1.04m/s

u = 1.04/9.8 =0.11

Si un barco navega en el mismo sentido de la corriente de un rio, consume menos combustible que cuando va en sentido contrario d
aleksley [76]

Answer:

La respuesta a tu pregunta esta abajo.

Explanation:

Cuando un barco navega en un río en el sentido de la corriente, la velocidad que lleva más el impulso que le proporciona la corriente, hace que avance más rápido llegando más pronto a su destino sin tanto esfuerzo del motor. Por lo que gastaría una menor cantidad de combustible.

Cuando el barco se desplaza en sentido contrario a la corriente del motor, la corriente del río hace que su desplazamiento neto sea menor ya que el barco avanza y el río lo regresa un tramo y el esfuerzo del motor el mayor.

En estas condiciones aunque el barco tenga que recorrer la misma distancia que en el caso anterior, en realidad debería sumarse la distancia que lo regresa la corriente y por lo tanto el combustible gastado sera mayor.
