Answer to Question 1

D

Answer to Question 2

If an object has only (pure) translational motion every particle in it has the same instantaneous velocity, which means that the object is not rotating. An object may have only (pure) rotational motion - motion about a fixed axis if all of the particles of the object have the same instantaneous angular velocity and travel in circles about the axis of rotation.

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.
