You do it by the pressure difference it causes in the medium. Even in transversal waves, you usually need different units than meters because the wave has electric and magnetic vectors and not really any height to speak of.
you measure the amount of excursion from the equilibrium (no wave) level of whatever parameter is fluctuating.
Answer:
73 degree
Explanation:
Angle of incidence = 17 degree
According to the laws of reflection, the angle of incidence is equal to the angle of reflection.
So, angle of reflection = 17 degree
Angle from the surface = 90 - 17 = 73 degree
The answer is A, genetic factors...conditioning. I just took the test. Good luck!!
The answer might be B i hope is helps
Answer:
Every characteristic property is unique to one given substance. Scientists use characteristic properties to identify an unknown substance. Characteristic properties are used because the sample size and the shape of the substance does not matter.
Explanation:
A characteristic property is a chemical or physical property that helps identify and classify substances. The characteristic properties of a substance are always the same whether the sample being observed is large or small. Examples of characteristic properties include freezing/melting point, boiling/condensing point, density, viscosity and solubility.
