A kilogram is a unit of mass. A meter is a unit of measurement, a Liter is volume and a kelvin is temperature
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.
You can separate a mixture of salt and sand by...
First combing the mixture with water and mix thoroughly until the salt dissolves..
Then you could let the sand settle at the bottom of the salt water, so you can strain salt water to separate the sand from salt water...
To get salt... you would heat up the water to let it evaporate. When all the water is evaporated, the salt will be left behind
Answer:
=16.49 L
Explanation:
Using the equation
P1= 0.6atm V1= 30L, T1= 25+273= 298K, P2= 1atm, V2=? T2= 273
P1V1/T1= P2V2/T2
0.6×30/298= 1×V2/273
V2=16.49L
