Answer:

B. Negative externality

Explanation:

An externality is defined as a benefit or a loss that occurs to a third party due to some external reasons. The party has no control over the creation of the benefit or loss. It can be both negative or positive. Negative externality is a loss caused to the party whereas positive externality is a benefit caused to the party.

Here, the river is being polluted due to paper manufacturing industry. It means that the river is incurring a loss due to an external factor. Hence, this situation would be considered as negative externality.

Explain why a solar eclipse occurs only during a new moon.
Dennis_Churaev [7]

An eclipse of the Sun (or solar eclipse) can only occur at New Moon when the Moon passes between Earth and Sun. If the Moon's shadow happens to fall upon Earth's surface at that time, we see some portion of the Sun's disk covered or 'eclipsed' by the Moon.

A string of lights in a series circuit is not working. Which of the following is most likely the cause?
Talja [164]

Answer:

B. a light bulb burned out and "closed" the circuit.

Explanation:

Unscrew one bulb. If the other bulbs turn off, it is a series circuit. A light bulb glows when electrons flow through it. As the electron flow increases, the brightness increases.

When lights are attached in parallel, each light is on its own circuit to the power source. If one filament burns out, it has no effect on the remaining lights, as they each continue to be in a closed circuit with the power source.

Although we have discussed single-slit diffraction only for a slit, a similar result holds when light bends around a straight, t
QveST [7]
<h2>Width of hair is "1.96 10⁻⁵ m"</h2>

Explanation:

  • For this diffraction problem they tell us that it is equivalent to the diffraction of a single slit, which is explained by the equation
  •      a sin θ =±  m λ
  • Where the different temrs are: “a” the width of the hair, λ the wavelength, θ the angle from the center, m the order of diffraction, which is the number of bright rings (constructive diffraction)  
  • We can see that the diffraction angle is missing, but we can find it by trigonometry, where L is the distance of the strand of hair to the observation screen and "y" is the perpendicular distance to the first minimum of intensity
  •      L = 1.25 m 100 cm/1m   = 125 cm
  •      y = 5.06 cm  
  •     Tan θ = y/L
  •     Tan θ = 5.06/12
  •      θ = tan⁻¹ ( 0.0405)
  •      θ =  2.32º
  • With this data we can continue analyzing the problem, they indicate that they measure the distance to the first dark strip, thus m = 1
  •     a = m λ / sin θ
  •     a = 1 633 10⁻⁹ 1.25/sin 2.3
  •     a = 1.96 10⁻⁵ m  
  •     a = 0.0196 mm
  • Hence, "the width of the strand of hair is   1.96 10⁻⁵ m" is correct answer
