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 
Hello!
When the Northern Hemisphere is tilted toward the sun, latitudes between the equator and 90°N (the North Pole) are experiencing summer.
.Internal energy is the total potential and kinetic energies in a substance, and thermal energy is the part of internal energy that can be transferred to another substance. Thus, option "C" is correct.
<h3>What is the thermal energy Meaning?</h3>
Thermal energy, is internal energy present in a system in a form of thermodynamic equilibrium probity by its temperature.
Thermal energy cannot be transformed to useful work as easily as the energy of systems that are not in conditions of thermodynamic equilibrium.
Thus, option "C" is correct

Because the top layer of a pool will be warmer than the bottom layer, that why filtration is important to cycle the water evenly.
Answer:
In order to hit the same point with the second ball, you should throw it at an angle of 18° above the horizontal.
Explanation:
Horizontal reach formula for projectiles tells us
where 
is the initial velocity and 
the angle above the horizontal.
Since for both shots the reach must be the same, we have
.
