In this problem, we are dealing with induced emf in a loop.

**Part A.**

Induced emf:

$\overline{){\mathbf{\epsilon}}{\mathbf{=}}{\mathbf{-}}{\mathbf{N}}\frac{\mathbf{\u2206}{\mathbf{\varphi}}_{\mathbf{B}}}{\mathbf{\u2206}\mathbf{t}}{\mathbf{=}}{\mathbf{-}}{\mathbf{N}}\frac{\mathbf{\u2206}\mathbf{B}\mathbf{A}\mathbf{c}\mathbf{o}\mathbf{s}\mathbf{\theta}}{\mathbf{\u2206}\mathbf{t}}}$

A single loop of wire with an area of 0.0840 m^{2 }is in a uniform magnetic field that has an initial value of 3.80 T, is perpendicular to the plane of the loop and is decreasing at a constant rate of 0.140 T/s.

Part A.

What emf is induced in this loop?

Express your answer using two significant figures.

Part B.

If the loop has a resistance of 0.800, find the current induced in the loop.

Express your answer using two significant figures.
