Homework Statement
When two capacitors are connected parallel,
the equivalent capacitance is 2.6 μF. If the
same capacitors are reconnected in series, the
equivalent capacitance is one-fourth the ca-
pacitance of one of the two capacitors.
PART A: Determine the capacitance of the...
Homework Statement
The air temperature above the coastal areas
is profoundly influenced by the large specific
heat of water. One reason is that the heat
released when 1 m3 of water cools by 1◦C will
raise the temperature of an enormously larger
volume of air by 1◦C.
Calculate this...

Homework Statement
A rectangular plate has an area of 76 cm2.
If the temperature increases by 199 ◦C,
calculate the increase in the area. Use
2 × 10−6 (◦C)−1 as an average coefficient of
linear expansion. Ignore terms of second or-
der.
Answer in units of cm2.
