Problem 1243

The resistance \(\mathrm{R}\) of a given size of wire at constant temperature varies directly as the length \(\ell\). It is found that the resistance of 100 feet of number 14 copper is \(0.253\) ohm. Construct a table of values for the given lengths of number 14 copper wire assuming the temperature is constant.

Expert verified

Here is the table of resistance values for the given lengths of number 14 copper wire, assuming a constant temperature:
Length (feet) | Resistance (ohms)
--------------|-------------------
50 | 0.1265
100 | 0.253
150 | 0.3795
200 | 0.506
250 | 0.6325

A falling body strikes the ground with a velocity \(\mathrm{v}\) which varies directly as the square root of the distance s it falls. If a body that falls 100 feet strikes the ground with a velocity of 80 feet per second, with what velocity will a ball dropped from the Washington monument (approximately 550 feet high) strike the ground?
