places her hand in a solenoid whose magnetic field is 5.00 T directed
perpendicular to the plane of the bracelet. The electrical resistance
around the circumference of the bracelet is 0.200 Ohms.
An
unexpected power failure causes the field to drop to 1.50 T in a time of
20.0 ms. Find (a) the current induced in the bracelet and (b) the power
delivered to the resistance of the bracelet. (What does this problem
imply about the risks of wearing metall
ic objects when working in
regions of strong magnetic fields?).
i.
If the plates are separated by a distance d = 0.015 mm,
determine the potential difference between the plates.
ii.
If a dielectric with dielectric constant k = 5.0 is placed between
the two pla
tes, determine the new potential difference. Assume
the dielectric completely fills the space between them
iii.
