Explanation:
Shale is fine sediment pressed together to form rock.
Sandstone is larger (sand-grain-sized) sediment cemented together to form rock.
Shale erodes faster, as evidenced by the second attachment. That attachment shows erosion of a rock face consisting of interbedded shale and sandstone. The shale has receded significantly, leaving the sandstone layers with space between them.
The acceleration of snow is 32 m/.
<u>Explanation:</u>
According to Newton's second law of motion, the force acting on any object is directly proportional to the product of mass and acceleration acting on the object.
So if the object is a snowblower driver with mass 1250 kg and the force acting on it is 40000 N, then the acceleration of the snow can be determined from the ratio of force to mass.
Force = Mass × Acceleration
Acceleration = =
Thus, the acceleration of the snow is 32 m/.
