Explanation:
Wave is defined as a disturbance or oscillation that travels through space-time, accompanied by a transfer of energy. Wave motion transfers energy from one point to another, often with no permanent displacement of the particles of the medium.
The velocity of wave is equal to the product of its wavelength and frequency (number of vibrations per second). Longitudinal waves like sound waves travel through a medium.
Therefore, a wave move from a layer of high velocity to that of a lower velocity the wavelength changes (that is, decreases) as it moves.
Im sorry i looked it up and said you coldnt convert so.... : /
The answer is C. ionic compounds, compared to another hard compound which is the covalent bond, the structure of the ionic compound is lattice or crystalline in form thus less room for imperfections on its structure compared to the latter choices.
Answer:
Pressure is a quantity that may be measured in a variety of units such as atm and bar. However, the Pascal is used to measure pressure in the SI system. One Pascal is the pressure exerted perpendicularly on an area of one square meter by a force of magnitude one Newton.
