Answer to Question 1

ANS: A
Buoyancy occurs when an object is submerged in water. The object feels lighter than it is above water. The Bernoulli principle, Dalton's law, and Boyle's law relate to how gases or fluids vary with changes in pressure, volume, or temperature.

Answer to Question 2

ANS: C
Atmospheric pressure is highest at sea level. An increase in altitude will cause atmospheric pres-sure to decrease, which leads to a decrease in the force of gravity.

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.
