Light shines through atomic Hydrogen gas. It is seen that the gas absorbs light readily at a wavelength of 91.33 nm.
 
  What is the level to which the Hydrogen is being excited by the absorption of light of this wavelength? Assume that the most of the atoms in the gas are in the lowest level. A) 25
  B) 27
  C) 22
  D) 32

Question 2

A 1-kg ball is released from a height of 6 m, and a 2-kg ball is released from a height of 3 m. Air resistance is negligible as they fall.
 
  Which of the following statements about these balls are correct? (There could be more than one correct choice) A) As they reach the ground, the 1-kg ball will have more kinetic energy than the 2-kg ball because it was dropped from a greater height.
  B) As they reach the ground, the 1-kg ball will be moving faster than the 2-kg ball.
  C) Both balls will reach the ground with the same speed.
  D) Both balls will reach the ground with the same kinetic energy.
  E) Both balls will take the same time to reach the ground.
