Answer:
The water from head of 20m or above is brought in open or closed conduit. Traditionally wooden blades are used as turbine on which water jets are strike upon, jets rotates the bigger wheel mounted on smaller wheel. There is continuos feed of grains in between grinds into finer particles.
The answer is behaviorism !! <3
B, he has to apply less force to lift the box because the mass has decreased.
The equation for force is
F=ma
If m is decreased by half, then f decreases as well. It takes less force to push a lighter object across the floor.

Answer:
The acceleration of the crate is 
Explanation:
Recall the formula that relates force,mass and acceleration from newton's second law;
Then in our case, we know the force applied and we know the mass of the crate, so we can solve for the acceleration as shown below:
