In this figure, a cork attached to a string floats in an inverted jar filled with water. Compare the cork to a helium balloon attached to a car seat. (See the Physics on Your Own box on page 164 of your textbook). As the jar shown here is accelerated, you would expect the cork to behave:
a. similar to the balloon in an accelerating car.
b. the opposite of the helium balloon in an accelerating car.
c. in a way that is unrelated to the balloon.
Question 2
Inside a space station in orbit around Earth:
a. there is no gravity because of the height of the station far above Earth.
b. there is no gravity because the station is in orbit.
c. gravity appears absent because everything is moving and accelerating together.
d. objects have no mass because they are in orbit.
e. gravitational effects feel the same as on Earth.
