A loop of wire is at the edge of a region of space containing auniform magnetic field B_vec. The plane of the loop isperpendicular to the magnetic field. Now the loop is pulled out ofthis region in such a way that the area A of the coil inside the magnetic field region isdecreasing at the constant rate c. That is, \frac{dA}{dt} = - c, with c > 0.The induced emf in the loop is measuredto be V. What is the magnitude B of the magnetic field that the loop was in?Part BFor the case of a square loop of sidelength L being pulled out of the magneticfield with constant speed v (see the figure), what is the rate of change ofarea c = -\frac{da}{dt}?

1,800 ft

Step-by-step explanation:

Rebecca will walk in the pattern of a regular polygon with 'n' sides and internal angles of 160 degrees (180 at a straight line - 20 degrees from each turn).

The equation that describes the internal angle of a regular polygon is:

For A = 160 degrees:

If each side is 100 ft long, the total distance that Rebecca has walked is:

She walked 1,800 ft.
