Answer:
x= -0.2 or -1/5
Step-by-step explanation:
42+5X=41
Subtract 42 from both sides:
42+5X=41
-42 -42
You are left with:
5x=-1
Now divide 5 by both sides to isolate x:
5x= -1

5 5
x=-0.2 or -1/5
Answer:
20pi or 62.83
Step-by-step explanation:
when r=4
pi r^2
16pi
when r=6
pi r^2
36pi
36pi-16pi=20pi or 62.83
Initial Conditions:
length=L= 10 cm = (10*10⁻²)m
Diameter=D= 2 cm= (2*10⁻²)m
Radius= r= 0.01m
Area=A= π*r²/2 =1.57*10⁻⁴ m²
Resistance=R= 600 ohm
So, from initial conditions we find resistivity(р)
R=рL/A
R*A /L=р
(600)*(1.57*10⁻⁴)/(10*10⁻²)=р
р=0.942 Ω m
<span>As, material remains same so resistivity(p) doesn't change
</span>Lenght= L1= 15 fm= 15*10⁻¹⁵ m
Diameter= D1 = 5 cm= 5*10⁻² m
Radius= r= 0.025 m
Area= A1= π*r²/2 =9.8125*10⁻⁴ m²
R=р*L1/A1
R=(0.942 )*(15*10⁻¹⁵ )/(9.8125*10⁻⁴)
R=1.44*10⁻¹¹ Ω
Answer:
Step-by-step explanation:
Givens
L = 4/5 m
w = 3/5 m
Formula
A = L * w
Solution
Area = 4/5 * 3/5
Area = (4 *3 ) / (5 * 5)
Area = 12/ 25 m^2
