Answer:
weathering and erosion
Explanation:
Sand forms when rocks break down from weathering and eroding over thousands and even millions of years. Rocks take time to decompose, especially quartz (silica) and feldspar. Often starting thousands of miles from the ocean, rocks slowly travel down rivers and streams, constantly breaking down along the way.
Answer:
As Per Given Information
Mass of Car 4000 Kg
Acceleration of car 20m/s²
we have to find the force required to make the car car accelerate at given magnitude .
Using Formulae
- Force = Mass × Acceleration
On Putting the value we obtain
↝ Force = 4000 × 20
↝ Force = 80000 N
↝ Force = 80KN
So, the force required to maintain the given acceleration is 80 KiloNewton .
Answer:
Average speed or just speed
Explanation:
Average speed is the total distance an object travels divided by the total amount of time it took to travel the distance.
