Explanation:
A guitar string vibrates when we strikes it. It starts vibrating in several modes simultaneously. It stretches between the saddle and the nut. This distance represents one-half wavelength.
Now if we consider that the string forms a circle, then we have an interpretation of an electron which vibrates in the orbit surrounding the nucleus. We are aware that electrons have wavelength. If the circumference of the orbit happens to be the integer multiple of wavelength
, then the orbit is "allowed" since "the electron will retraces its own path."
This explains the line spectrum and not a continuous spectrum.
A line spectrum refers an electron that jumps between the specific energy levels, thus producing only specific colors.
<span>The Answer would be </span><span>A)The concentration cannot be increased.</span><span> </span>
<span>The only statement that states a fact about metals is the first option, letter A. They are shiny and bend without breaking. Choices B-D are wrong because metals are not insulators but are god conductors of heat and electricity. Metals can be flattened but they are not brittle.</span>
Because its in group one....which only lose or gain electrons.....thus it will only have oneelectron to fulfill its octect rule
C
Speed is the time rate at which Sue covers the distance. It is derived by dividing the total distance covered by the total time taken to cover the distance . Usually SI unit for speed is km/h or mph or m/s.
Explanation:
Speed is also referred to as velocity- so the two are synonymous.
Acceleration is the rate at which speed is increasing. It is usually given by SI unit m/s². The opposite of acceleration is deceleration which is the rate at which speed is decreasing.
Distance is the measurement, in meters of kilometers or miles or yards..etc, that has been covered from one point to another.
