A microwave can reheat 1 cup of coffee in 30 seconds. It takes a coffee-maker 10 minutes to brew 12 cups of coffee. If the coffee-maker requires 900 watts of power and the microwave requires 1200 watts of power, does it require more energy to brew 12 cups with the coffee-maker or reheat 12 cups of coffee in a microwave?

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?
