In a room with a single light source on the ceiling, Kofi stands directly under the light, and Mirembe stands in the corner. There is a tall cabinet between them, blocking the direct line of sight. If Kofi raises a balloon filled with helium and lets it go, will Mirembe be able to see the balloon rising, and why?
Provide a very brief response.
Mirembe will not be able to see the balloon rising immediately after Kofi lets it go because the cabinet is in the way, obstructing her line of sight. When objects are between two points of observation, they can prevent a clear view of one point from the other. However, if the balloon rises high enough above the cabinet, it may become visible to Mirembe, depending on the height of the cabinet and the balloon's ascending path. As the balloon is filled with helium, a lighter-than-air gas, it will rise towards the ceiling. Once it exceeds the height of the cabinet, it could potentially enter Mirembe's field of vision, allowing her to see it.
