Answer:
potential energy=ε Qq/r. Putting values of charge along with sign and calculating the potential energy will tell whether the resultant force is attractive or repulsive.
Explanation:
potential energy=ε Qq/r
q and Q are charges on each particle
So in case the particles have attractive force between them, one particle will be negative and the other will be positiive. The result will be negative.
In case the particles have repulsive forces, the charge on both particles will be either positive or negative. The result will be positive
The three construction crafts that require a MINIMUM of a 4-year college degree are:
- Buildings
- Infrastructure
- Industrial.
<h3>What is construction science degree?</h3>
Construction Science courses is known to be one that helps the student to have an introduction to building codes, electrical and mechanical systems, construction planning, site work, etc.
This is one that prepare students for a four-year time in colleges and universities and after this four years, when they pass their final exams, they are given a construction science degree which can be used in buildings, infrastructure and industrial field.

Answer:
Rated power = 1345.66 W/m²
Mechanical power developed = 3169035.1875 W
Explanation:
Wind speed, V = 13 m/s
Coefficient of performance of turbine, 
= 0.3
Rotor diameter, d = 100 m
or
Radius = 50 m
Air density, ρ = 1.225 kg/m³
Now,
Rated power = 
or
Rated power = 
or
Rated power = 1345.66 W/m²
b) Mechanical power developed = 
Here, A is the area of the rotor
or
A = π × 50²
thus,
Mechanical power developed = 
or
Mechanical power developed = 3169035.1875 W
