<u>Answer:</u>
The amount of the lighted side of the moon you can see is the same during "how much of the sunlit side of the moon faces Earth".
<u>Explanation:</u>
The Moon is in sequential rotation with Earth, and thus displays the Sun, the close side, always on the same side. Thanks to libration, Earth can display slightly greater than half (nearly 59 per cent) of the entire lunar surface.
The side of the Moon facing Earth is considered the near side, and the far side is called the reverse. The far side is often referred to as the "dark side" inaccurately but it is actually highlighted as often as the near side: once every 29.5 Earth days. During the New Moon the near side becomes blurred.
Answer:
All these laws give the relationship between two quantities of the gas among V (volume), p (pressure) and T (temperature), keeping the third one constant - however the two quantities change for each law
Explanation:
Calling:
p = gas pressure
V = gas volume
T = gas temperature (in Kelvin)
We have:
- Boyle's law: the pressure and the volume of a gas kept at constant temperature are inversely proportional. Mathematically,
- Charles's law: the temperature and the volume of a gas kept at constant pressure are directly proportional. Mathematically,
- Gay Lussac's law: the temperature and the pressure of a gas kept at constant volume are directly proportional. Mathematically,
<h2>Answer:</h2>
Low melting points and electrical conductivity in solids are not common properties of ionic solids.
<h3>Explanation:</h3>
In ionic compounds the electrons involved in the bonding are tightly packed under the influence of electrostatic force of attraction. So the movement of these electrons is very difficult.
In the melting point the bond breaking between the atoms is involved. Hence in case of ionic compound there is a high amount of energy needed to break the ionic bonds.
Electrical conductivity involves the free movement of electrons which is impossible in ionic solids.
So low melting points and electrical conductivity in solids are not common properties of ionic solids.
Answer:
(1.) gamma rays. (2.) X-rays. (3.) ultraviolet. (4.) visible light. (5.) infrared.
(6.) radio waves
Explanation:
Notice that these wavelengths span an enormous range. The wavelengths of gamma rays can be smaller than the size of an atomic nucleus, while the wavelengths of radio waves can be many meters (or even milometers) long. Visible light spans only a very narrow range of wavelengths, from about 400 nano meters at the blue (violet) end to about 700 nano meters at the red end.
