Given Information:
Current = I = 28 A
distance between wires = r = 2.0 m
Required Information:
Magnetic field = B = ?
Answer:
B = 12x10⁻⁶ T
Step-by-step explanation:
Biot-Savart Law is given by
B = μ₀I/2πr
Where μ₀ is the permeability of free space, I is the current flowing through the wire and B is the magnitude of the magnetic field produced.
We are asked to find the magnetic field midway between the wires so r/2 = 1
B = 4πx10⁻⁷*28/2π*1
B = 6x10⁻⁶ T
since the same amount of current flows in both wires therefore, equal amount of magnetic field will be produced in both wires
B = 2*6x10⁻⁶ T
B = 12x10⁻⁶ T
Therefore, the net magnetic field midway between the two wires is 12x10⁻⁶ T.
Mass = 1.2 kg = 1200 grams.
Volume = mass/density = 1200 cm3.
Hope this helps!
The gas that gives Neptune and Uranus its amazing blue color is methane
Answer:
The divergence on the sensor shows the magnitude of the charges
Explanation:
This will increase as length increases since it is said to be proportional to the length. note that test charge is always positive and charge on the grid is positive as indicated (1 nC)
The frequency of a wave is just the reciprocal of the period.For this one . . .
Frequency = 1/(period) = 1/(5 sec) = 0.2 per sec (0.2 Hz) .
