These four surfaces are opaque; that is they reflect or absorb certain rays of light determine the color
masya89 [10]
In the first figure, the surface absorbs all colors except for green light, which is reflected: so, the surface will appear as green to our eyes, because green is the only color which is reflected by that surface.

Similarly, in the  second figure, the surface absorbs all colors except for blue, and so the surface will appear blue to our eyes.

In the third figure, the surface absorbs all colors, so it will appear black to our eyes (because no colors are reflected, and black=absence of colors).

In the fourth figure, all colors are reflected: this means the surface will appear white to our eyes (white= sum of all colors).

How much energy in Joules (J) would an electric heater that draws 9.5 A when connected to a 120 V supply use if the heater were
leonid [27]
<h2>Energy used by heater is 8.21 x 10⁶ J</h2>

Explanation:

Energy = Power x Time

Power = Voltage x Current

Voltage = 120 V

Current = 9.5 A

Power = Voltage x Current

Power = 120 x 9.5 = 1140 W

Time = 2 hours = 2 x 60 x 60 = 7200 s

Energy = Power x Time

Energy = 1140 x 7200

Energy = 8208000 J

Energy used by heater is 8.21 x 10⁶ J

La velocidad de la luz en el vacío es c= 3000.000 km\s la luz del sol tarda en llegar a la tierra 8 minutos y 14 segundos
ehidna [41]

La velocidad correcta de la luz en el vacío es  300.000 km/s .

La distancia = (velocidad) x (duración de tiempo)

Duración de tiempo = 494 segundos, porque cada minuto = 60 segundos

La distancia = (300.000 km/s) x (494 s)

<em>La distancia = 148.200.000 km</em>
