An electron is in the ground state of an infinite well (a box) where its energy is 5.00 eV. In the next higher level, what would its energy be? (1 eV = 1.60  10-19 J)
 
  A) 1.25 eV B) 10.0 eV C) 15.0 eV D) 20.0 eV E) 2.50 eV

Question 2

A solid object has a volume density 0 at a temperature of 315 K. The coefficient of volume expansion for the material of which it is made is 7.00  10-5 K-1.
 
  What will be its density (in terms of 0 at a temperature of 425 K, assuming that it does not melt and that its thermal properties do not change with temperature?

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
