The value of constant in terms of Force, k, A, V and ρ is x = ln (F /kAρV ).
<h3>What is opposing force?</h3>
The force which tends to oppose motion of fluid in forward direction like shear stress in liquids and friction force in solids
A body moving through the air at speed V, experiences the retarding force.
Force = kAρVˣ
where A is the surface area, ρ is the density of air and k is the numerical constant.
Taking natural logarithm both sides,
ln F = ln (kAρVˣ)
ln F = x ln (kAρV)
x = ln F / ln (kAρV)
x= ln (F /kAρV )
x= ln F - ln (kAρV)
Thus, the value of constant is deduced in terms of Force , k, A, V and ρ.

Answer:
Lateral inversion
Explanation:
When an object is placed in front of a plane mirror, the appearance of the object on the plane mirror appears as a reversal of the object. This effect is known as lateral inversion.
Lateral inversion occurs as a result of the fact that light is reflected by a plane mirror. The image formed by the plane mirror is as far behind the mirror as the object is in front of it. Hence lateral inversion occurs because of the way our brains perceive images on a plane mirror. The mirror image of symmetrical letters and objects do not show lateral inversion.

Answer:
By a factor 9
Explanation:
The intensity of a sound wave is proportional to the square of the amplitude of the wave:
where
I is the intensity
A is the amplitude of the wave
In this problem, the amplitude of the sound wave is increased by a factor 3:
A' = 3A
So the intensity would change by
So, the intensity would increase by a factor 9.
