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:
P₂ = 252 W
Explanation:
The electrical power is
P = V I
The potential difference is
V = I R
I = V / R
Let's replace
P = V² / R
Let's use the given values to calculate the resistance of the bulb
R = V² / P
R = 120²/75
R = 192 ohm
This resistance value does not depend on the applied voltage, so it is constant
Let's calculate the power in Europe
P₂ = V₂² / R
P₂ = 220²/192
P₂ = 252 W
the bulb dissipates much more power
