If Jinho is standing at the bottom of a well-lit hill and Anika is standing at the top, each with a clear line of sight to the other, and an opaque balloon is released from the top of the hill, will Jinho see the balloon pass in front of Anika's face as it floats down? Respond very briefly.
Jinho will see the balloon pass in front of Anika's face. As the balloon is being released from the top of the hill and is opaque, it will block Jinho's view of Anika as it descends the hill, given that there is a clear line of sight between Jinho and Anika. Gravity will cause the balloon to float or fall downwards, along the path between Jinho and Anika, obstructing Jinho's view of Anika temporarily when it passes her face.
