A bar magnet is dropped vertically with its upper end, a North
pole, through a metal ring. If the ring is viewed from above the
rings center the induced current in the ring A) will flow clockwise
and be increasing. B) will flow clockwise and be decreasing. C)
will flow counter-clockwise and be increasing. D) will flow
counter-clockwise and be decreasing. E) The induced current will be
zero.

Find an equation for the plane that
(a) is perpendicular to v=(1,1,1)v=(1,1,1) and passes through
(1,0,0).(1,0,0).
(b) is perpendicular to v=(1,2,3)v=(1,2,3) and passes through
(1,1,1).(1,1,1).
(c) is perpendicular to the line
l(t)=(5,0,2)t+(3,−1,1)l(t)=(5,0,2)t+(3,−1,1) and passes through
(5,−1,0).(5,−1,0).
(d) is perpendicular to the line
l(t)=(−1,−2,3)t+(0,7,1)l(t)=(−1,−2,3)t+(0,7,1) and passes through
(2,4,−1).

The magnetic flux through a metal ring varies with
time t according to ΦB= 10 at 3 -5 bt2, where Φ is in webers, a =
6.00 s-3, b = 5.0 s-2, and t is in seconds. The resistance of the
ring is 5.00 Ω. For the interval from t = 0 to t = 2.00 s,
determine the maximum electric power induced in the
ring.
please explain in
details.

A 54-cm-long, 500 g bar rotates in a horizontal plane on an axle
that passes through the center of the bar. Compressed air is fed in
through the axle, passes through a small hole down the length of
the bar, and escapes as air jets from holes at the ends of the bar.
The jets are perpendicular to the bar's axis. Starting from rest,
the bar spins up to an angular velocity of 200 rpm at the end of 12...
