The answer to the question would be the second choice: <span>The west component is a negative number, and the north component is a positive number. It can be based upon in a Cartesian coordinate system wherein the coordinate is located in the second quadrant. </span>
<h3><u>Answer;</u></h3>
C) decreases; increases
<h3><u>Explanation;</u></h3>
- As we move through the visible spectrum, red to violet (right to left in the image), the wavelength <u><em>decreases</em></u> and the frequency <em><u>increases</u></em>.
- <em><u>Electromagnetic spectrum comprises of electromagnetic waves arranged in the order of increasing or decreasing frequency and wavelength.</u></em>
- These electromagnetic waves includes; <em><u>radio waves, microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays. </u></em>
- In electromagnetic spectrum as you move from left to right, <em><u>that is from the radio waves towards the gamma rays, the wavelength decreases as the frequency increases; while from gamma rays towards the radio waves the wavelength increases while the frequency decreases.</u></em>
Given:
heat generated by John's cooling system,
= 45 W (1)
If ρ, A, and v corresponds to John's cooling system then let
be the variables for Mike's system then:
![\rho = 9.5\rho_{1}](https://tex.z-dn.net/?f=%5Crho%20%20%3D%209.5%5Crho_%7B1%7D)
![\rho_{1} = \frac{\rho}{9.5}](https://tex.z-dn.net/?f=%5Crho_%7B1%7D%20%20%3D%20%5Cfrac%7B%5Crho%7D%7B9.5%7D)
![v_{1} =3.5 v](https://tex.z-dn.net/?f=v_%7B1%7D%20%3D3.5%20v)
Formula use:
Heat generated, ![H = \rho A v^{3}](https://tex.z-dn.net/?f=H%20%3D%20%5Crho%20A%20v%5E%7B3%7D)
where,
= density
A = area
v = velocity
Solution:
for Mike's cooling system:
=
⇒
=
× A ×
= 4.513
A ![\rho](https://tex.z-dn.net/?f=%5Crho)
Using eqn (1) in the above eqn, we get:
= 4.513 × 45 = 203.09 W
