A) Find the area of the region enclosed by the
parabola and the line
B) Write down an integral to compute the volume of the solid
obtained by rotating the region below the curve about the y-axis.
You do not need to evaluate the integral.
C) Write down an integral to compute the volume of the solid
obtained by rotating the region below the curve about
the x-axis. You do not need to evaluate the integral.
The area enclosed by the wire loop in the figure below is
reduced from 31 cm2 to 12 cm2 in a time interval of 0.11 s. The
magnitude of the magnetic field is 0.53 T. Find the emf induced in
the wire.
