Answer:
0.002T
Explanation:
It is given that,
Distance between two parallel wires, d = 5 mm = 0.005
Current in each wire, I = 60 A
Let B is the magnitude of the magnetic field at a point that is between the two wires and 2.0 mm from one of the two wires.
calculating the magnetic field due to first wire is given by :
The magnetic field due to second wire is given by :
Let B is the net magnetic field from wire A, so,
Correct answer is A.
In a parallel circuit, the voltage is same across all the branches however the current in each branch is different and depends on the resistance of that branch. The higher the resistance, the lower the current.
In a series circuit, the voltage across each resistive element is different and depends on the resistance of that element. Higher the resistance, larger will be the voltage drop. However, the current throughout the series circuit is the same as there is only path in a series circuit.
Points to Remember:
1) In series circuit current remains the same and voltage varies
2) In parallel circuit voltage remains the same and current varies

Answer:
Transmission of telephone signals
Explanation:
Fiber optics are used for the transmission of telephone signals.
Answer:
The angle with the positive x axis 61.31°
Explanation:
It is given that, a vector in the x-y plane has a magnitude of 25 m and x component of 12 m.
x component of the vector, base = 12 m
Magnitude of hypotenuse, H = 25 m
We need to find the angle with the positive x axis. Let it is given by θ such that :
θ = 61.31°
So, the angle with the positive x axis 61.31°. Hence, this is the required solution.
