To develop this problem it is necessary to apply the concepts performed to the absolute pressure based on the reference pressure (atmospheric) and the pressure that is generated due to the height of the column of the measured liquid.
In mathematical terms the previous concept can be expressed as
Where
Atmospheric Pressure
Density
g = Gravitational acceleration
h = Height
Our values are given as
g = 9.8m/s
Replacing we have then that
Therefore the absolute pressure in the test section is 99.9019kPa
Gravity is directly proportional to the product of the two. Masses and inversely proportional to the square distance between the two masses.
They’re both describing factors of something
When it comes to wave behavior, there are parameters called wavelength and frequency. These two are related by speed of the radiowave. Radiowaves are electromagnetic waves which travels as fast as light. The wavelength is the distance while frequency is the reciprocal of time. When you multiply them both, you get the electromagnetic wave's speed. The equation is c = wavelength*frequency, where c is the speed of light equal to 3 x 10^8 m/s.
3 x10^8 m/s = wavelength/104.9 x 10^6 Hz (Hertz is 1/s)
wavelength = 2.86 meters
