In kindergarten, we learn red, orange, yellow, green, blue, indigo, and violet.

But the truth is that the rainbow, or true white light, contains EVERY COLOR that the human eye can detect.

Sure, ROYGBIV is in the rainbow.  So are amber, aqua, beige, blond, canary, coral, ebony, emerald, flax, fuchsia, gold, heliotrope, ivory, jade, khaki, lemon, maroon, navy, olive, pink, rose, salmon, tan, umber, verdigris, wisteria, saffron, and millions of others ... some without names.

If a distance-time graph contains the point (4, 15), what does that tell you about the runner?
serg [7]

Explanation:

It is given that there is distance time graph. The slope of any distance time graph will give the speed or velocity of the object.

In the context, it is seen that there is a point in the distance - time graph. And the values of the point in the graph is (4,15).

Now here, the distance is plotted in the  ordinate or the vertical y-axis while time is plotted in the abscissa or the horizontal x-axis.

Thus the point (4,15) tells us that the object has traveled 15 units in time equal to 4 seconds.

The armature windings of a dc motor have a resistance of 3.0 Ω. The motor is connected to a 120V line, and when the motor reach
svlad2 [7]

Answer:

0.6 A

Explanation:

As the motor gears towards full speed, the voltage of the circuit tends to become the difference that exists between the line voltage and the that of the back emf. Remembering Ohm's law, we then apply it to get the final, lower current that is based on the reduced voltage Ef. We use the provided resistance in the question, that is 3 ohms.

Ef = (120 V) - (117 V) = 3 V

If = Ef/R = (3 V) / (5.0 Ω) = 0.6 A

1. In a particular experiment to study the photoelectric effect, the frequency of the incident light and the temperature of the
shutvik [7]

Answer: 1. B. The number of electrons emitted from the metal per second increases.

2. The maximum speed of the emitted electrons increases.

The stopping potential increases

Explanation:

Photoelectric effect is simply referred to as the emission of electrons that occurs when there's an electromagnetic radiation. An example of such electromagnetic radiation is when material is being hit by light.

Assuming that the light incident on the metal surface causes electrons to be ejected from the metal, the number of electrons emitted from the metal per second increases if the intensity of the incident light is increased.

Also, if the initial light incident on the metal surface causes electrons to be ejected from the metal, the maximum speed of the emitted electrons increases and the stopping potential increases.
