Answer:
The velocity is
Explanation:
From the question we are told that
The velocity of the water in the pipe is 
The pressure inside the pipe is 
The pressure at the nozzle is 
The density of water is 
For the height 
where
is height of water in the pipe
and
is height of water at the nozzle
Generally Bernoulli equation is represented as

=> 
Where
is the velocity of the water at the nozzle
Now making
the subject

substituting values


<span>A) cools down, slows down. When you put water in the freezer, it cools down and then the particles reduce their speed until they eventually form a solid by freezing.</span>
I think that is clearly in the name. It will use 850W at 100% load if the cos¿ = 1
In Newton's Third law of motion, the 'action' and 'reaction' forces act on different objects. That's why they don't cancel each other out and always result in zero force.
