Yes, sedimentary rocks are formed from remains of tiny sea animal/Non-Sea animal/Plants.
The average force exerted by the runner is 200N.
A force is an influence that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
When a force is exerted across a distance to an item, work is accomplished. This implies that the total energy of an object will be impacted when a force is applied to it over a distance.
Work = Force x Distance
Force = work / distance
Force = 2000 J / 10 m
Force = 200 N
Hence, the average force exerted by the runner was 200N.

Answer:
D).happens when soil is weakened by water and seismic waves
Explanation:
Liquefaction is a phenomenon in which the strength of the soil weakens due to the earthquake or any other load. The solid behaves like a liquid. Liquefaction of soil below structures cause lot of damage during Earthquakes.The soil looses stiffness due to seismic waves and water.
Thus, the correct option is D.
