Answer:
The statements to choose from are not shown in your question, but find below some characteristics of these three main phases, which may help you choose the right answers you are seeking.
Explanation:
Solid: The matter that constitutes it maintains a fixed volume and shape, with the particles that compose it close together and relatively fixed into place.
Liquid: The matter that constitutes it maintains a fixed volume, but has a variable shape that adapts to fit its container. Its particles are still close together but move freely.
Gas: The matter that constitutes it has both variable volume and shape, adapting both to fit its container. Its particles are neither close together nor fixed in place.
Efficiency is completing a task as fast a possible the the least amount of effort.

Answer:
Explanation:
Magnetic field due to circular wire at the center = μ₀ I / 2 r
I is current and r is radius . μ₀ = 4π x 10⁻⁷.
field B₁ due to inner loop
B₁ = 4π x 10⁻⁷ x 12 / 2 x .20
= 376.8 x 10⁻⁷
Field due to outer loop
B₂ = 4π x 10⁻⁷ x I / 2 x .30
For equilibrium
B₁ = B₂
376.8 x 10⁻⁷ = 4π x 10⁻⁷ x I / 2 x .30
I = 18 A.
The direction should be opposite to that in the inner wire . It should be anti-clockwise.
