Answer:
The pressure at point 2 is
Explanation:
From the question we are told that
The speed at point 1 is
The gauge pressure at point 1 is
The density of water is
Let the height at point 1 be then the height at point two will be
Let the diameter at point 1 be then the diameter at point two will be
Now the continuity equation is mathematically represented as
Here are the area at point 1 and 2
Now given that the are is directly proportional to the square of the diameter [i.e ]
which can represent as
=>
where c is a constant
so
=>
=>
Now from the continuity equation
=>
=>
Generally the Bernoulli equation is mathematically represented as
So
=>
substituting values
The correct option is (D) Gamma ( 
)
Explanation:
Now this question is a tricky one because all of these options are somehow involved in radioactive decay; however, in this case the SYMBOL is required NOT the elements. There are three symbols involved in radioactive decay, which are:
1. α for alpha decay
2. β for beta decay
3. γ for gamma decay
In the options only one symbol is present which is gamma. Hence option (D) Gamma ( ) is the correct answer.
-i
