The weight of the plane is (mass) x (acceleration of gravity).
Neither of these changes when the plane rises from the ground.
Its weight on the ground is equal to (the same as) its weight in the air.
C. something that has mass and takes up space
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


Answer:

Explanation:
Given that:
- magnetic field intensity,

- kinetic energy of electron,

- we have mass of electron,

<em>Now, form the mathematical expression of Kinetic Energy:</em>




<u>from the relation of magnetic and centripetal forces we have the radius as:</u>
