which objects are opaque? check all that apply.\ntextbook\ntrack shoes\nlight bulb\nbasketball\nlampshade

Brief Explanations:

Opaque objects do not allow light to pass through them. A textbook, track shoes, and a basketball are made of materials that block light. A light bulb emits light but is not opaque as light passes through its glass (when considering its transparency in the context of the question's intent - assuming the question is about the object's ability to block light like a regular object you'd interact with, not its function as a light - emitter). A lampshade is often translucent (allowing some light to pass through and scatter) or in some cases if very thick fabric might seem opaque but typically in basic science definitions for such questions, textbook (solid paper/pages), track shoes (leather/synthetic materials that block light), and basketball (rubber/leather covering that blocks light) are considered opaque.

Answer:

textbook, track shoes, basketball
