what does the velocity of a wave mesure https://goo.gl/search/What+dies+the+velocity+of+a+wavw+measure
Wave Parameters: Wavelength, Amplitude, Period, Frequency ... Speed and Wavelength. ... But, the speed of a wave has nothing to do with the amplitude of its crests and troughs. Speed is measured by the distance the wave travels in a certain amount of time. Specifically, it's measured in meters per second.
I believe the correct answer from the choices listed above is the second option. Analgesics are the drugs that kill pain by blocking impulses at specific receptor sites of the brain and spinal cord. Analgesics<span> are drugs that alleviate pain without causing anesthesia. Hope this helps.</span>
The element from those four that is a noble gas is krypton.
The extent of dissociation into hydrogen ions in water. A strong acid dissociates completely into hydrogen ions in water whereas a weak acid only dissociates partially
Answer:
NaI
Explanation:
In I₂, HI and IBr, both atoms are nonmetals and they form covalent bonds in which electrons are shared.
In NaI, Na is a metal and I a nonmetal, so they form an ionic bond, where Na loses an electron to form Na⁺ and I gains an electron to form I⁻. Anions and cations are attracted to each other through electrostatic forces.
Since ionic bonds are stronger than covalent bonds, more energy is required to break them in the melting process, thus having higher melting points.
All in all, NaI is the one with the highest melting point.
