The magnitude r, measured on the richter scale, of an earthquake of intensity i is defined as requalslog startfraction upper i over upper i 0 endfraction , where upper i 0 is a minimum intensity used for comparison. if the intensity of an earthquake was 10 superscript 6.08times upper i0, what was the magnitude on the richter scale?

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
