Answer:
100 resident/km
Step-by-step explanation:
In order to find the population density, we have to calculate the area of the township first.
We know that:
L = length = 5 km
W = width = 4 km
So the area of the township is
A=L\cdot W = 5 \cdot 4 = 20 km^2A=L⋅W=5⋅4=20km
2
Now we can find the population density by using
d=\frac{N}{A}d=
A
N
where N is the number of residents, and A is the area.
Substituting N = 2000, we find:
d=\frac{2000}{20}=100 res./km^2d=
20
2000
=100res./km
2
so, 100 residents per kilometer squared
Answer:
a) Approximate the change in R is 0.5 ohm.
b) The actual change in R is 0.04 ohm.
Step-by-step explanation:
Given : The total resistance R of two resistors connected in parallel circuit is given by 
To find :
a) Approximate the change in R ?
b) Compute the actual change.
Solution :
a) Approximate the change in R
and 
is decreased from 12 ohms to 11 ohms.
i.e. 
is increased from 10 ohms to 11 ohms.
i.e. 
The change in R is given by,
b) The actual change in Resistance
When resistances are charged, 
Change in resistance is given by,
L=N (because opposite angle of parllalogram is euqal)
4X-25= 3X+18
X =43
there for angle N=3×43+18
N=147
Now we know that the sum of the corresponding angle of a parllalogram is 180
N+M=180
M=180-147
M=33
A and B are equal to 27^-1
