Question

select the correct answer.
physics is explicitly involved in studying which of these activities?
a. the mixing of metals to form an alloy
b. the metabolic functions of a living organism
c. the motion of a spacecraft under gravitational influence
d. the depletion of the atmospheric ozone layer due to pollutants
e. the killing of cancerous cells by radiation therapy

Explanation:

• Option A relates to materials chemistry, not explicit physics.
• Option B is a biology/biochemistry focus.
• Option C directly uses Newtonian gravitation and kinematics, core physics topics.
• Option D falls under environmental chemistry/earth science.
• Option E is primarily a medical physics application, but the most explicit direct physics study is spacecraft motion.

Answer:

C. the motion of a spacecraft under gravitational influence
