The driving force behind the resource depletion is due to pollution and activties done by man. Pollution has drive a depletion of resource as this is a way of having to destroy the environment, such as having water pollution which will contaminate water, depleting additional resources. Another thing is the activity done by man, such as cutting of trees, using dynamites in order to catch fish and dumping of wastes in water, all of these contributes into having resources to deplete and lose.

Answer:

Sound waves from the source of sound are trapped by the pinna and collected to the to the auditory canal where they are concentrated to the middle ear consisting of the ear drum (stirrup, anvil, hammer). Here the sound waves are amplified further to the semi-circular canal where these waves are converted to impulses and sent to the brain via the auditory nerve for interpretation

Which equation represents the polar form of x2 + (y – 6)2 = 36?

yanalaym [24]

Answer:

$r^2-12r\sin\theta=1$

Explanation:

We need to write the polar form of the given equation :

$x^2+(y-6)^2=36$

Put $x=r\cos\theta$ and $y=r\sin\theta$

$x^2+(y-6)^2=36\\\\(r\cos\theta)^2+(r\sin\theta-6)^2=36\\\\r^2\cos^2\theta+r^2\sin^2\theta+36-12r\sin\theta=36\ \ [\because (a-b)^2=a^2+b^2-2ab]\\\\r^2(\cos^2\theta+\sin^2\theta)-12r\sin\theta=0\\\\\text{We know that}, \cos^2\theta+\sin^2\theta=1\\\\r^2-12r\sin\theta=1$
