3. what is physics?
4. what are some useful appliances and objects that depend on physical science?
5. what are some career options in physical science?

Explanation:

1. Galileo improved the telescope and made astronomical observations that supported the heliocentric model, challenging traditional views.
2. Marie Curie discovered the elements polonium and radium, and made significant contributions to radioactivity research.
3. Physical science is the study of non - living systems, encompassing physics and chemistry among other fields.
4. Chemistry is the science that deals with the composition, structure, and properties of matter, and the changes it undergoes.
5. Physics is the science that studies matter, energy, and the interactions between them.
6. Useful appliances and objects that depend on physical science include light bulbs (based on electrical and optical principles), refrigerators (thermodynamics), and smartphones (electronics and materials science).
7. Career options in physical science include physicist, chemist, materials scientist, engineer, and science educator.
