Answer:
The magnitude of force is 1.86 N and the direction of force is towards the other wire.
Explanation:
Given:
Current flowing through each power line, I = 130 A
Distance between the two power lines, d = 40 cm = 0.4 m
Length of power lines, L = 220 m
The force exerted by the power lines on each other is given by the relation:
Substitute the suitable values in the above equation.
F = 1.86 N
Since the direction of current flowing through the power lines are opposite to each other, so the force is attractive in nature. Hence, the direction of force experienced by the power lines on each other is towards the each other.
Answer:
Current, I = 1200 A
Explanation:
It is given that,
Length of the cylinder, l = 40 m
Radius of the metal wire, r = 4 mm = 0.004 m
Voltage source, V = 16 V
Resistivity of metal,
We know that the resistivity of any metal is given by the formula as :
R = 0.01336 ohms
Using ohm's law :
I = 1197.60 A
or
I = 1200 A
So, the current flowing in the cylindrical wire is 1200 A. Hence, this is the required solution.

E= 0.6
Constant sigma is 5.6704004× 10∧ (-8)
The area is LC = 2× .8 = 1.6m∧2
to convert degrees celcious to Kelvin =303K
The equation is
P = e ? AT∧4.
Then the answer is 460 watts.
Melting: as mantle material rise toward the divergent plate boundary the pressure is reduced which causes melting
