Explanation:
The water cycle is a parameter of the hydrosphere that always remains constant. Life on Earth and its sustenance is possible because of this cycle. The continuous evaporation, condensation, and precipitation of water provides for the many processes involved in Earth's natural surroundings. Without the water cycle, life would cease to exist.
It is speeding up because more distance is covered every second.
Explanation:
The car can be described to be speeding up because more distance is covered every second.
From what we understand about velocity and acceleration, the car is accelerating through the ramp.
It's velocity is increasing with every second it covers.
This will invariable reduce the time between each distance covered.
Originally, the toy car starts with a low initial velocity or speed. As it gains acceleration, the speed will increase and more distance covered per seconds.
This is why the dots clustered towards the end of the diagram. The positions are getting closer and distance reducing per seconds.
