Answer and Explanation:
A. Given that Design 1A will cost $1.7 million to build and $175,000 per year to maintain
Given that Design 1B will cost $3.6 million to build and $40,000 per year to maintain
Both designs are assumed to be permanent
To find ROR using AW based rate of return equation, we find present value of each design and equate them:
Each design is permanent so
Present value of perpetuity:
Design 1A= 1700000+175000/r
Design 1B = 3600000+40000/r
=1700000+175000/r=3600000+40000/r
135000/r=1900000
Cross multiply
r=135000/1900000
r= 0.0710
r=7.10%
B Given that ROR=7.10% and MARR is 25%
MARR>ROR
Hence we reject both designs
Limited government licenses that create a monopoly do so because the license is an entry barrier.
Hence, option C is correct.
What do you mean by monopoly in economics?
Monopoly can be defined as a situation where there is a dominance of a single seller in the market. It is opposite to the concept of perfect competition. An unregulated monopoly possesses market power and can influence prices in the overall sector.

- No Produce Replacement Option
- Very Difficult to Enter in Market.
- Pricing Control.
- Government Driven.
- Natural Monopoly.
There are usually three types of monopoly

Answer:
E = 1.20 × 
N/C
V = 1800 V
x = 0.058 m
Explanation:
given data
radius = 15 cm
net charge = 3 × 
C
electric potential decreased = 500 V
solution
we get here electric field at the sphere’s surface that is
electric field at the sphere’s surface E = 
............1
put here value
electric field at the sphere’s surface E = 
E = 1.20 × N/C
and
potential on surface of sphere is
V = 
................2
V = 
V = 1800 V
and
now we get distance that is x
and we know here
ΔV = V(x) - V ..............3
substitute here value
-500V = 
-500 V = 
solve it we get x
x = 0.058 m
