<span>D) the Mass of water needs to be in a closed system to control the boiling. With an open system, you can no longer measure the water vapor output and be sure that the water vapor in the bottle is equal to the water vapor in the air or beyond. It is only through the closed system that you can measure the volume, the mass difference and ensure that both are in equilibrium</span>
Answer:
A. Karst topography
Explanation:
Karst topography are characterised by dissolution of limestone and other carbonate rocks.
Answer:
Your answer is they are produced by P and S waves.
Explanation:
These waves are known as primary and secondary waves. When these two waves have passed through the earthly body, the next wave that follows is the surface wave. They move slower than body waves and they are also more destructive because they are larger. Hope this helped :)
Answer:
The satellite is being accelerated towards the Earth by the gravity of the Earth, but because it's moving sideways too quickly, it keeps missing the Earth. So it keeps falling, but not getting closer. This is what it means to "orbit". In orbit you have two forces balanced, gravity and centripetal acceleration
hope it helped!
