In the formation of mountain ranges and all other landforms, there is always a cycle involved. As one mountain comes up, another land gets pushed down into the hot mantle, where the rock will melt. Due to convection currents, the tectonic plates move and their boundaries cause them to interact with each other. As mountain ranges are formed, other land gets pushed up forming what we know are mountains, with rising magma from other parts of the world solidifying creating new rock to fill the empty space.
A snow blower is more powerful because it's easier, and it moves large amounts of snow easily. Shoveling uses all of <em>your power.</em> It can be difficult and it takes a long time to get the snow off of your lawn.
Therefore, using a snow blower is more powerful than using a shovel.
I hope this helped!
Answer:
+5m/s
Explanation:
When doing the math we figure out that e is going to be slowing down at -4m/s² for 5 seconds. In total he is slowing down -20m/s which we take from the total speed of +25m/s to get his current new speed.
