Flattening is a example of a physical change.
Hope this helps! :D
publish a book in which he explained his heliocentric theory.
Explanation:
The heliocentric theory is the one according which the Sun is in the center of our Solar Sistem and the planets go around it.
Previously to this theory (before Copernicus) the prevalent theory was geocentrism accordind which it was the earth who stood in the center and all the other celestial bodies went around it.

☑ Examples;
- Projectile motion
- Circular motion
- Free fall motion
Explanation:

To set up a stable and clear interference pattern, two conditions must be met: The sources of the waves must be coherent, which means they emit identical waves with a constant phase difference.
Answer:
Gravitational potential energy (GPE) = 107.8J
Explanation:
Gravitational potential energy (GPE) = mgh
Where mass(m) = 11kg
Acceleration due to gravity(g) = 9.8m²/s
height = assumed to be 1m
Force(F) = mg
Force(F) = 11×9.8 = 107.8N
Gravitational potential energy (GPE) = 107.8×1
= 107.8J
