Default From the Extra question pool: The dipole


"Lloyd" wrote in message
...
A coaxial cable lying over the peak of a roof is the same length on each

side.
It weighs one third of a pound per foot. On one end hangs an Extra

holding a
dipole, and on the other end a weight equal to the weight of the Extra.

The
dipole weighs two ounces per inch. The cable is as long (in feet) as the

age
of the Extra (in years), and the weight of the Extra (in ounces) is the

same as
the age of the Extra's mother. The combined age of the Extra and his

mother is
seventy years. One half of the weight of the Extra, plus the weight of

the
dipole, is one forth as much as the weight of the weight and the weight of

the
cable. The Extra's mother is half as old as the Extra will be when he is

three
times as old as his mother was when she she was half as old as the Extra

will
be when when he is as old as his mother will be when she is four times as

old
as the Extra was when he was twice as old as his mother was when she was

one
third as old as the Extra was when he was old as his mother was when she

was
three times as old as the Extra was when he was one fourth as old as he is

now.

How long is the dipole?


that can't be from the question pool... they are all multiple guess and you
didn't give me 4 answers with 3 stupid looking ones to throw out!
