<span>If you faced the situation when popcorn is heated over a flame and the kernel burst opened the thing which caused that is definitely : the air and water vapor which remain in the kernell have expanded.
Hope that helps.

Answer:
Flow rate 2.34 m3/s
Diameter 0.754 m
Explanation:
Assuming steady flow, the volume flow rate along the pipe will always be constant, and equals to the product of flow speed and cross-section area.
The area at the well head is

So the volume flow rate along the pipe is

We can use the similar logic to find the cross-section area at the refinery

The radius of the pipe at the refinery is:



So the diameter is twice the radius = 0.38*2 = 0.754m
Answer:
It will emerge at its initial speed not a slower speed.
Explanation:
It will emerge at the initial speed because the medium at the point of emergence is the same as the medium before incidence.
Light moves at a constant speed in any particular medium. Hence, the speed of light in air is constant in air and the speed of light in glass is constant in glass.
Answer:

Explanation:
From the question we are told that:
Length 
Distance apart 
Electron Transferred 
Therefore
Total Charge
Since Charge on each electron is

Therefore


Generally the equation for Charge density is mathematically given by

Where
Area


Therefore


Generally the equation for Electric Field in the capacitor is mathematically given by



The correct answer would be B.
