If the weight of an object with mass m is given by W = mg on Earth's surface, what will its weight be inside an airplane at an altitude of 35,000 feet?
a. The same.
b. It will be slightly less because g is somewhat smaller at that height.
c. It will be slightly more because of the increased potential energy.
Question 2
Which of these statements is true?
a. The value of g is 1.
b. The value of g is exactly constant at any given distance from Earth's center.
c. Even at a given distance from Earth's surface, the value of g can vary slightly.
d. The value of g changes a great deal from place to place at a given elevation on Earth's surface.
e. The value of g is exactly constant all over Earth's surface.
