Answer: Acids turn the indicator red, pink, orange, and yellow, while bases turn it green, blue, and purple.
The solution and answer are well written in the Pic above.
The magnetic force between two wires is 0.052 N which is attract each other.
We need to know about magnetic force on a current-carrying wire formula to solve this problem. The magnetic force on two wires with same direction of current is
F = μ₀ . I1 . I2 . L / ( 2π . r )
where μ₀ is vacuum permeability (4π×10‾⁷ H/m) F is the magnetic force, I is current, L is the length of wire, r is distance of 2 wires.
From the question above, we know that:
L = 25 m
r = 6 cm
I1 = I2 = 25 A
By substituting the parameter, we get
F = μ₀ . I1 . I2 . L / ( 2π . r )
F = 4π×10‾⁷ . 25 . 25 . 25 / (2π . 0.06)
F = 0.052 N
Hence, the force between two wires is 0.052 N which is attract each other.

The correct answer is (B) Consumptive.
Explanation:
"Consumptive use" is the term used in the field of Water Science to define "the <span>part of water withdrawn that is evaporated, given off by plants, used by crops, consumed by humans or livestock, or otherwise removed from the immediate water environment. It is also referred as water consumed." Hence the correct answer is (b) Consumptive.
