What are constellations?

Explanation of Solution
The sky of the Earth is adorned with the stars. A group of stars is found in a same pattern in the night sky for a period of time.
A group of stars in the sky connected with by imaginary lines are called constellations. Astronomers grouped the stars in the night sky and named them to identify them. Greek and Arabian astronomers pioneered in the astronomy.
There are about 88 official constellations. The stars in the constellations do not have connections among themselves with some exceptions and they are located from the sun at different distances.
Conclusion:
The stars in the night sky are grouped as Constellations.

- Suppose there are two transformers between your house and the high-voltage transmission line that distributes the power. In addition, assume your house is the only one using electric power. At a substation the primary of a step-down transformer (turns ratio = 1:23) receives the voltage from the high-voltage transmission line. Because of your usage, a current of 51.1 mA exists in the primary of the transformer. The secondary is connected to the primary of another step-down transformer (turns ratio = 1:36) somewhere near your house, perhaps up on a telephone pole. The secondary of this transformer delivers a 240-V emf to your house. How much power is your house using? Remember that the current and voltage given in this problem are rms values.arrow_forwardThe human eye is most sensitive to light having a frequency of about 5.5 × 1014 Hz, which is in the yellow-green region of the electromagnetic spectrum.
