Answer:
864 mT
Explanation:
The magnetic field due to a long straight wire B = μ₀i/2πR where μ₀ = permeability of free space = 4π × 10⁻⁷ H/m, i = current in wire, and R = distance from center of wire to point of magnetic field.
The magnitude of magnetic field due to the first wire carrying current i = 2.70 A at distance R which is mid-point between the wires is B = μ₀i/2πR.
Since the other wire also carries the same current at distance R, the magnitude of the magnetic field is B = μ₀i/2πR.
The resultant magnetic field at B is B' = B + B = 2B = 2(μ₀i/2πR) = μ₀i/πR
Now R = 2.50 cm/2 = 1.25 cm = 1.25 × 10⁻² m and i = 2.70 A.
Substituting these into B' = μ₀i/πR, we have
B' = 4π × 10⁻⁷ H/m × 2.70 A/π(1.25 × 10⁻² m)
B = 10.8/1.25 × 10⁻⁵ T
B = 8.64 × 10⁻⁵ T
B = 864 × 10⁻³ T
B = 864 mT
Hypotheses and theories related to each other since hypotheses are used in creating a theory. Hypotheses are explanations for some phenomenon that are still proposed. When these are validated and proved, they are accepted by the public as theories and are used to explain natural phenomenon.

Answer:Dark minerals rich in iron and magnesium separate from light minerals rich in silica and aluminum.
Explanation: Metamorphic rocks are rocks formed as a result of the transformation of other existing rocks which can be Igneous or Sedimentary rocks,this transformation process is called METAMORPHISM. During metamorphism,rocks under Serious levels of stress which can lead to the separation of materials.
During this separation process,Dark minerals rich in iron and magnesium are separated from light minerals rich in silica and aluminum.
