Question

select the correct answer.
a cruise ship makes its way from one island to another. the ship is in motion compared with which reference point?
a. the passengers on the ship
b. the captain of the ship
c. a lighthouse on a nearby island
d. the cargo inside the hull of the ship

Explanation:

To determine if an object is in motion, we compare its position relative to a reference point. For the cruise ship:

• Option A: Passengers on the ship move with the ship, so relative to them, the ship is not in motion.
• Option B: The captain is on the ship, so relative to the captain, the ship is stationary.
• Option C: A lighthouse on a nearby island is a fixed point. As the ship moves from one island to another, its position changes relative to the lighthouse, so the ship is in motion relative to the lighthouse.
• Option D: The cargo is inside the ship, moving with it, so relative to the cargo, the ship is not in motion.

Answer:

C. a lighthouse on a nearby island
