Questions using star
Problem 1
Which statement correctly uses star in The Solar System, Gravity & Orbits?
- star: A body that emits light through its internal energy processes, such as the Sun.
- Gravity stops at the top of the atmosphere.
- A bright reflected object must be a star.
- One illustrative result establishes every real condition and needs no further evidence.
Answer and explanation
star: A body that emits light through its internal energy processes, such as the Sun.
A body that emits light through its internal energy processes, such as the Sun. A is the better basic explanation. Gravity changes the moving satellite’s direction rather than vanish outside the atmosphere. Without the modeled force, its motion would not follow the same curved path around Earth. The drawing still omits precise speed, distance scale, and other influences needed for a full numerical prediction.
