• Then the pulse decays ( away ).
• Later on, interest in theoretical ideas about the nature of matter waned ( or subsided ).
• The curve slopes down from 0°C toward the eutectic point.
• The charge and the voltage decay with the same time constant.
• When the speed falls ( or drops ) below this level, ...
• The observation curves fall off steeply.
• The current grows to two maxima in opposite directions and dies away to two minima during each cycle.
