Answer :
Final answer:
The AP Physics 1 Exam's multiple-choice section contains 50 questions, where students are tested on various physics principles including projectile motion with an optimum angle of 45° for maximum range.
Explanation:
The multiple-choice section of the AP Physics 1 Exam consists of 50 questions. Therefore, the correct answer to the question is c) 50. This section is designed to test students' understanding of foundational principles of physics, which includes topics such as mechanics, electric circuits, and waves. Each of these questions typically comes with four answer options, and students must select the one that best completes the statement or answers the question. For example, one of the common topics is projectile motion, where a common question may ask about the optimum angle for maximum range, which is 45°.
