Pretend an object is set sliding on a huge frictionless plane in contact with the surface of Earth as shown. Once the object is set in motion it will
 
  1) theoretically slide to the right forever
  2) slide back and forth
  3) slow down and stop
 
  because
  4) of its inertia.
  5) gravitational force decreases with increasing distance.
  6) the object is sliding uphill and then downhill relative to the round Earth.

Question 2

As a spaceship nears the Moon, its mass
 
  1) varies slightly with distance,
  2) increases,
  3) decreases,
  4) remains unchanged,
 
  while the Moon's gravitation force on the ship
  5) increases.
  6) decreases.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).

Many people have small pouches in their colons that bulge outward through weak spots. Each pouch is called a diverticulum. About 10% of Americans older than age 40 years have diverticulosis, which, when the pouches become infected or inflamed, is called diverticulitis. The main cause of diverticular disease is a low-fiber diet.
