If you step outside when the temperature is well below freezing, you can bet it will not be raining. You are more likely to see snow if there is any precipitation at all. Water in the clouds is so cold that it turns into ice crystals. What are some of the physical differences between rain water and ice crystals such as snow?

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponentβs 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?
