Final answer:
A scientist in the physical sciences, such as physics or chemistry, would study questions related to matter and energy. For example, they might study the impact of gravity on planetary motion, atomic structure, or light propagation.
Step-by-step explanation:
A scientist working in the physical sciences would most likely study questions that involve matter and energy. This can encompass a wide range of topics, but examples would include asking "How does gravity affect the motion of planets?", "What is the structure of an atom?", or "How does light propagate through different materials?". These questions all concern the basic principles of physics and chemistry, which are primary disciplines in the physical sciences.
