However, the effect that global warming will cause on earth are extremely serious. There are many effects that will happen in the future if global warming continues. That includes polar ice caps melting, economic consequences, warmer waters and more hurricanes, spread of diseases and earthquake.
Term RMS refers to the mathematical Root Mean Square which is an average of peaks and valleys of a materials surface profile. Ra stands for roughness average. Ra is a average of only peaks; therefore, to get an Ra, multiple your 3.2 to 6.3 by 2 to get 6.4 to 12.4 Ra. AF Kenton.
The rms. value is expressed from zero to 70.7% of the peak amplitude for a single frequency.The rms. value is calculated for the spectrum.In a periodic time wave, the rms. value must be calculated in the FFT. It will represent the overall energy of the FFT.rms.
