Explanation:it is beause they are sharper and also have less surface area and therefore more pressure
It's called sedimentation. And erosion is when the rock is worn away by the water, and wind and becomes sediment.
Explanation:
Newton's second law simply says that the net force on an object is equal to the object's mass times its acceleration.
∑F = ma
For example, think of a game of tug-of-war, in which two teams pull on a rope in opposite directions.
If the forces are equal (balanced), then the net force is 0 N, so Newton's second law tells us that the rope's acceleration is 0 m/s².
If the forces are not equal (unbalanced), then the net force is not 0 N, and the rope will accelerate in the direction of the net force.
The answer is c ok
I wrote this for 20 word rule
W = Fxd
However, when you carry it, the actual bag of mulch isnt changing height so the only work done on the actual bag is when you lift it.
W = 45N x 1.2m
= 54J
