Answer:

5.90 ft/s^2

Explanation:

There are mixed units in this question....convert everything to miles or feet

    and hr  to s

28 mi / hr = 41.066 ft/s

Displacement = vo t + 1/2 at^2

         599       =  41.066 (8.9)  + 1/2 a (8.9^2)

                      solve for a = ~ 5.90 ft/s^2

larisa86 [58]
The correct answer is
<span>the flux increases because the magnitude of b increases.

In fact, the magnetic flux is given by
</span>\Phi_B = B A \cos \theta
<span>Where B is the intensity of the magnetic field, A the area enclosed by the coil and </span>\theta the angle between the direction of B and the perpendicular to the area A.
We can see that since in the problem the intensity of B increases, and the direction remains unchanged, then the magnetic flux increases as well.
