The bright-line spectrum of an element in the gaseous phase is produced as 1. protons move from lower energy states to higher energy states 2. protons move from higher energy states to lower energy states 3. electrons move from lower energy states to higher energy states 4. electrons move from higher energy states to lower energy states

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?

If y gets smaller as x gets bigger and y have an relationship?

When you hold a rectangular object, how does the area of the side that is resting on your hand affect the pressure and the force that the object exerts?
