The
following data represent the breaking strengths of samples of 20
gauge insulated copper wire fron three different suppliers. The
researcher is interested in findinf evidence that the distribution
of breaking strength differs by supplier. Use the .01 significance

Canada Wire Products processes copper into wire. It makes
16-gauge and 14-gauge wire. During April, the joint costs of
processing the aluminium were $365,000. There were no beginning or
ending inventories for the month. Production and sales value
information for the month were as follows:

A length of 20-gauge copper wire (of diameter 0.8118 mm) is
formed into a circular loop with a radius of 24.0 cm. A magnetic
field perpendicular to the plane of the loop increases from zero to
18.0 mT in 0.20 s. Find the average electrical power dissipated in
the process.

Copper has 8.5∙1028 free electrons per cubic
meter. A 71.0 cm length of 12-gauge copper wire that is 2.05 mm in
diameter carries 4.85 A of current. (a) How much time does it take
for an electron to travel the length of the wire? (b) Repeat part
(a) for 6-gauge copper wire (diameter 4.12 mm) of the same length
that carries the same current. (c) More generally, how does
changing the diameter of the wire that carries a given amount...
