Explain why stars appear to move across the sky each night why are some stars only visible doing certain seasons-?
All the motions and changes you see are a result of four simple facts: 1.The Earth is spinning on its axis, one turn every 24 hours. 2.The Moon is orbiting around the Earth, one orbit every 27.3 days. 3.The Earth and all the other planets are orbiting the Sun, all in the same direction, and all in roughly the same plane (i.e. it's like they are all laid out on a large dinner plate with the Sun at the centre). The outer planets orbit more slowly than the inner planets. 4. The stars are stationary. (They do, in fact, move very quickly. But they are so far away that the motion appears to us to be too slow to perceive without special instruments.)

Explain why stars appear to move across the sky each night why are some stars only visible doing certain seasons?
Stars appear to move across the sky each night because the earth is moving, but not the stars. Also some stars are only visible during certain seasons because as the earth rotates, they become visible.
When is the constellation Hercules most visible?
Hercules can be best seen during the spring months. It first becomes visible in April and works its way across the sky to disappear in October.
Which red line shows the same action spectrum corrected for the unequal number of photons emitted across the visible spectrum?
The red line corrected for the unequal number of photons emitted across the visible spectrum would likely be a line that is flat or relatively constant across the visible spectrum. This correction aims to account for the differing sensitivity of the human eye to light of different wavelengths, providing a more accurate representation of how light exposure affects biological processes.
What is the basic mechanism responsible for emission of visible radiation in an LED?
by applying a voltage across the boundary of two semi-conductors electrons are forces to travel across the boundary. This boundary has a voltage drop and the electrons are required to lose a discrete amount of energy in crossing it. In the case of the light emitting diode, it is a energy in the range of visible light.

What are the Britain stone rings?
Stone rings and rows of stones are a common feature across Britain and parts of France. We don't know for sure what all of them were used for, though some of them definitely have an astronomical purpose. Some are arranged so that a certain star is visible on a certain night of the year. They mark the beginning of the seasons, so they may have been used for predicting when to plant crops. Rows of stones in northern France may have been used as a primitive seismometer for recording earthquakes (that region of France is prone to earthquakes.) As far as their age, we don't even know that for certain, though they certainly are several thousand years old.
