<em>The core accretion model Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula. With the rise of the sun, the remaining material began to clump together.</em>

Answer:
132.64m/s
Explanation:
Averagevelocity= distance/time
From the question, the distance d = 825m
time t = 6.22 secs
Using the above formula
We have
average velocity = 825/6.22
= 132.64m/s
The pressure exerted on the stone is
What is pressure?
- The force delivered perpendicularly to an object's surface per unit area across which that force is dispersed is known as pressure (symbol: p or P).
- A scalar quantity, pressure. It connects the normal force operating on the surface and the vector area element, which is normal to the surface. The scalar scale parameter is pressure.
- The pascal (Pa), or one newton per square meter, is the SI unit for pressure.
- A force is an effect that has the power to alter an object's motion. A motion of an object having mass to accelerate when it changes its velocity, for as when it moves away from rest. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both direction and magnitude.
Formula for pressure = Force / area
