Answer:
Fields and variables are proportional
Explanation:
To solve the problem we must first identify the Vector Intensity,
The intensity is given by:

We also know that the change given by the Intensity is always the square of the amplitude,
This is,

The intensity is <em>proportional</em> to the change exerted on 
That is to say that in turn the amplitus is <em>proportional</em> to the Intensity.
On the other hand, relating the two variables we have


In this way we can conclude that the electric field of intensity is also <em>proportional</em> to 
Answer:
5.95 ml
Explanation:
Given info
P1=2.9 atm
V1=8.21 ml
P2=4 atm
From Boyle's law we know that p1v1=p2v2 where p and v are pressure and volume respectively. This is at a constant temperature. Making v2 the subject of formula then
V2=p1v1/p2
V2= 2.9*8.21/4=5.95 ml
A resource, such as oil, that cannot regenerate in a reasonable amount of time, such as a human lifetime, is called a "nonrenewable" resource.<em> (A) </em>
Once it's gone, it's gone.
