The sunshine on the moon appears convex, straight (flat), or concave depending upon your vantage point. It is always the same porportion on the moon, but it looks differently because of the position of the Sun, Earth, and Moon at different times of the month. If you take a volleyball in a dark area, and shine a flashlight on the side of it, moving the ball and the light around will reproduce the moon phase effect, and give you a practical understanding of it.
The amount of the moon that is always lit except during a lunar eclipse is about half. This is because half of the moon is always illuminated by the sun due to the moon's orbit around the Earth.
During the New Moon phase, the moon is only up during the day but since it faces the sun it is not usually seen except when it passes in front of the sun. This is when a sloar eclipse occurs.
The light from the sun reflects light to the full moon as the sun is always just opposite the full moon except during the new moon time, where there is no moon to be seen.
You can't see the moon during the 12 to 30 hours before and after the New Moon. So that's anywhere from 1 to 2-1/2 days during the month, depending on the exact angle of the ecliptic to the horizon, and the moon's orbital inclination relative to the ecliptic. (Those things change from month to month.)
The moon is partially shadowed because it does not emit its own light; instead, it reflects sunlight. During most phases, only a portion of the moon's surface is illuminated by the sun, creating the varying shapes we see from Earth. This shadowed part becomes fully illuminated only during the full moon phase when the Earth is positioned between the sun and the moon, allowing the entire face of the moon to be lit up.
A hexagon could be any of those, and more than one at the same time. If it's regular, then it's all the others except 'concave'. On the other hand, if it's concave, then it's not any of the others.
Transition elements are ALL solid metals except for mercury (80Hg) which is a liquid.
A concave lens is thinner in the middle and thicker at the edges, causing light rays to diverge. A concave mirror, on the other hand, is curved inward like the inside of a bowl, causing light rays to converge at a focal point. Both have different optical properties and applications.
The elements in the first two groups and in the last 6 groups. Basically all the elements except the inner transition and transition elements.

A concave long board isn't really any different from any other board except that it has a certain amount of pressure added to the center of the board so the edges are higher up. This adds a little more responsiveness to the turning and also helps you stay on the board better then if it was flat. Other variations of this would be like a "W" type concave.
To find the number of sides of a convex polygon given the sum of all angles except one, we can use the formula: (n-2) * 180, where n represents the number of sides of the polygon. In this case, the sum of all angles except one is 2180 degrees. Therefore, we can set up the equation: (n-2) * 180 = 2180. Solving for n, we get n = (2180/180) + 2, which simplifies to n = 14. Hence, the polygon has 14 sides.
Rhenium is a transition metal. Like all of the transition metals except for mercury, rhenium is a solid at room temperature. It melts into a liquid at 3459 kelvin.
All of the transition metals are capable of forming multiple ions except for Zn, Cd and Ag.
Alkali metals are found only in the first family (column) in the periodic table.Copper is a transition metal.This site is GREAT for learning all about specific elements and their properties. It's basically a periodic table of elements, except the elements have all been linked to pages that have a pretty decent amount of information on each.http://www.ptable.com/
