Determine at what temperature aluminum will have the same resistivity as tungsten does at 24 ∘
c.

The resistivity of tungsten can be determined using the empirical equation
Rw = 48.0 (1 + 4.8297 × 10^−3 T + 1.663 × 10^−6 (T^2))
Input the temperature to get the resistivity

For aluminum, you can look for the empirical equation for its resistivity but what is available is a graph between resistivity and temperature. Simply use the graph to determine which temperature will result to the same resistivity of tungsten at 24 C.

I'll do it rn and then answer

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.
