Noble gases are used in many situations where a safe and constant environment must be maintained. For example, helium is used to provide a protective atmosphere for making fiber optics and semiconductors.Ā Argon is used to fill incandescent and flourescent light bulbs to prevent oxygen from corroding the hot filament.
Why are noble gases used in these situations?
Christine is investigating how potential energy transforms into kinetic energy by rolling a ball down a staircase.Ā Each stair in the staircase is the same height.Ā The arrow shows the direction of movement of the ball.
As the ball moves down the staircase, where has two-thirds of the ball'sĀ INITIALĀ potential energy been converted to kinetic energy?
