Answer:
Anemometers measure wind speed and wind vanes measure wind direction. A typical wind vane has a pointer in front and fins in back. When the wind is blowing, the wind vane points into the wind.Barometers, manometers and anemometers are all scientific instruments. Scientists use barometers and manometers to measure atmospheric pressure, while anemometers measure wind speed.
Explanation:
<span>Quantum mechanic model is based on mathematics. As per this theory the exact position and momentum of electron is impossible to understand. It uses complex shapes of orbitals called electron clouds. n describes the energy of an electron. Larger the value of n larger the distance of electron from the nucleus and larger the orbital. l describles the shape of orbital. Orbitals having same of value of n and different values for l are called subshells.</span>
Mass is never lost or gained in chemical reactions. We say that mass is always conserved. In other words, the total mass of products at the end of the reaction is equal to the total mass of the reactants at the beginning. This is because no atoms are created or destroyed during chemical reactions.
The answer will be the gravitational force, because if we weren't in the gravity of the sun we would also be floating around with not much purpose.
Answer: The donating of hydrogen ions is what makes an acid an acid. A base, however, is a substance that accepts hydrogen ions.
