<span>Water is never added to earth system. Water forever remains in the water cycle on earth, so it goes from the ground, to the air, to the rain, to the sea, and round and round continuously. This cycle means that there does not need to be new water added to the earth, because it recycles any water that already exists of its own accord.</span>
The uniform acceleration of the car is 4.485 m/s².
<h3>
Acceleration of the car</h3>
The uniform acceleration of the car is calculated as follows;
v² = u² + 2as
a = (v² - u²)/2s
where;
- v is final velocity = 41 m/s
- u is initial velocity = 28 m/s
- s is distance = 100 m
- a is acceleration = ?
a = (41² - 28²)/(2 x 100)
a = 4.485 m/s²
Thus, the uniform acceleration of the car is 4.485 m/s².

The speed of the water in the wider part will be 1.194 m/sec. Speed is a time-based quantity. Its SI unit is m/sec.
<h3> What is speed?</h3>
Speed is defined as the rate of change of the distance or the height attained.
The given data in the problem is;
The initial diameter is,
initial radius,
The initial crossection area;
The final crossection area;
The initial flow rate is;
R = density ×velocity ×area
The speed of the water in the wider part will be;
From the continuity equation;
Hence, the speed of the water in the wider part will be 1.194 m/sec.

Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE.
