Bird habitats include various habitat types: from the human-related environment (e.g., building area, park, rural area, farmland, and pond) to the natural-related environment (e.g., forestland, grassland, river, stream, and coastland).
Answer:
<em>| Fn | = 258 N</em>
Explanation:
<u>Net Force</u>
The net force vector is the sum of all the force vectors applied to a body.
There are four forces applied to a car:
325N to the north
175N to the south
465N to the east
255N to the west
To simplify the calculations, we find the net force by each axis separately, considering forces to the right and upward as positive.
Fx = 465 N - 255 N = 210 N
Fy = 325 N - 175 N = 150 N
The magnitude of the net force is:



| Fn | = 258 N
Answer with Explanation:
We are given that
Radius of solid core wire=r=2.28 mm=

Radius of each strand of thin wire=r'=0.456 mm=
Current density of each wire=
a.Area =
Where 
Using the formula
Cross section area of copper wire has solid core =
Current density =
Using the formula


Total number of strands=19
Area of strand wire=




b.Resistivity of copper wire=
Length of each wire =6.25 m
Resistance, R=
Using the formula
Resistance of solid core wire=
Resistance of strand wire=
B is the answer
16 x 6.0 = 96
