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.
Best Answer: To understand the meaning of true Root-Mean Square (RMS) one need to go to its mathematical and a more pragmatic physical definition. Since we are dealing with a changing quantity we need to compute its average value over a period, however it also has its positive and negative components.f it is not you will get false results from them if the load on a circuit is reactive such as a motor or if the wave shape is not a pure sine wave. True RMS instruments can correctly resolve various phase relationships and wave shapes to give you a true RMS reading of voltage and current.
