Answer:

A) 72° or 71.56°

Explanation:

We have two components on the X-axis and y-axis respectively. So we can use the tangent of the angle to be able to find the angle with respect to the horizontal component.

Ax = 2.5

Ay = 7.5

tan(α) = 7.5/2.5

\alpha = tan^{-1} (3)\\

α = 71.56°

Leto [7]

Answer:

a) counterclockwise

Explanation:

The Lenz's Law establish that the direction of the induced current is in an opposite direction, in comparison with the change od the magnetic flux.

\epsilon=-\frac{d\Phi_{B}}{dt}

Specifically, if the flux decreases the induced current is in a counterclockwise direction, if increases, the direction is in a clockwise direction.
