Step 1:
I'll solve this problem step by step, carefully following the LaTeX formatting guidelines:

Step 2:
: Calculate the Area of the Coil

- Number of loops: $$N = 20
- Area of the coil: A = a \times b = (0.0800 \mathrm{~m}) \times (0.120 \mathrm{~m}) = 9.60 \times 10^{- 3} \mathrm{~m}^{2}

Step 3:
: Determine the Rate of Change of Magnetic Flux

- Magnetic field: $$B = 3.00 \mathrm{~T}$$ (pointing into the page)
- Velocity: v = 5.00 \times 10^{- 2} \mathrm{~m/s}

Step 4:
: Calculate Induced EMF for Different Situations

- Induced Current: $$I = \frac{|\epsilon|}{R} = \frac{1.20}{8.00} = 0.150 \mathrm{~A}$$ (clockwise)
The induced EMF will depend on the fraction of the coil in the magnetic field. Situation 1: Coil Completely Outside the Field Situation 2: Half the Coil in the Field Situation 3: Coil Entirely in the Field Situation 4: 75% of Coil Exited the Field

Step 5:
: Explanation of Part (b)

The induced EMF depends on the rate of change of magnetic flux. When the coil is moving at a constant velocity, the rate of change of flux is the same whether 25% or 50% of the coil is in the field, resulting in the same induced EMF.

Final Answer

(a) See the detailed calculations in Step 3 (b) The induced EMF is the same because the rate of change of magnetic flux is constant during the linear motion of the coil.
