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:
3 sigma lower control limit = 0.0429
Explanation:
Given.
n = 100
days = 100
Number of defective bulbs = 600 defective bulbs
Let p = Process Average
p = 600/(100*40)
P = 600/4000
P = 0.15
q = 1 - p
q = 1 - 0.15
q = 0.85
3 sigma lower limit = p - 3*√(pq/n)
Using the above formula
Substitute in the values
3 sigma lower control limit = 0.15 - 3 * √(0.15 * 0.85/100)
3 sigma lower control limit= 0.15 - 3√0.001275
3 sigma lower control limit = 0.15 - 3* 0.035707142142714
3 sigma lower control limit = 0.15 - 0.107121426428142
3 sigma lower control limit = 0.04287857357185
3 sigma lower control limit = 0.0429 ---- approximated
Using lens equation;
1/o + 1/i = 1/f; where o = Object distance, i = image distance (normally negative), f = focal length (normally negative)
Substituting;
1/o + 1/-30 = 1/-43 => 1/o = -1/43 + 1/30 = 0.01 => o = 1/0.01 = 99.23 cm
Therefore, the object should be place 99.23 cm from the lens.
