The type of rock that's formed is igneous
Given the following data;
Force = 3000 Newton
Distance = 15 m
To find the work performed by the crane;
The work done by an object or body is calculated by multiplying the force acting on the object with the distance covered by the object.
Mathematically, work done is given by the formula;
Work done = force * distance
Substituting the values into the formula, we have
Work done = 3000 * 15
Work done = 45,000 Nm
In conclusion, the work performed by the crane is 45,000 Nm.
Answer:
Option C => They were deposited by glaciers.
Explanation:
Whenever we have a polished bedrock it is very important to know that the landscape can be found in places that are full of or has glacials. It is a process or phenomenon known as Glacial polish that causes large boulder in the area(even after the glaciers has melted). Therefore, option (C) is the correct Option in the question above.
Note that, the term " Glacial polish'' simply means the process in which the surface of bed rocks are grinded by graons and many or several pieces of rock.
Changes in the supply source or sediment supply can begin or end the life of a river.
<h3>What other factors can affect the life of a river?</h3>
Other factors that can affect the life of a river are;
- The kind of rocks present on the shores
- The source and supply of sediments.
Sediments deposited continually on the shores of a river can gradually edge the river away from it's course or cut it off from it's source.
Hence, it is right to state that Changes in the supply source or sediment supply can begin or end the life of a river.
