The Earth remains in orbit about the Sun, rather than falling in to the Sun, because
  1.it is outside of the gravitational influence of the Sun.
  2.the net force on the Earth is zero.
  3.although the Earth is constantly being pulled toward the Sun, it is always moving with a velocity component perpendicular to the direction that it is being pulled.
  4.none of these apply.

Question 2

A rigid object is rotating with an angular speed w > 0. The angular velocity vector w and the angular acceleration vector a are anti-parallel. The angular speed of the rigid object is
  1.clockwise and increasing.
  2.clockwise and decreasing.
  3.counterclockwise and increasing.
  4.counterclockwise and decreasing.
