4) The Richter scale is used for measuring the magnitude of an earthquake. The Richter magnitude R is given by the model R=0.67 log(0.37 E) + 1.46 Where E is the energy (in kilowatt-hours) released by the earthquake. An earthquake in Pakistan on June 8, 2007. released 132,372 kilowatt hours of energy, what was the earthquake's magnitude (to the nearest tenth)? a) 4.1 b) 4.3 d) 4.8 c) 4.6
