Review conceptual example 7 as an aid in solving this problem. a portable electric heater uses 18 a of current. the manufacturer recommends that an extension cord attached to the heater receive no more than 2.0 w of power per meter of length. what is the smallest radius of copper wire that can be used in the extension cord? (note: an extension cord contains two wires.)

Which situation will have the highest resistance? a.long wire and high temperatureb.short wire and high temperaturec.long wire and cold temperaturedshort wire and low temperature

Ascientific blank must be testable and capable of being proven false?

Aproduction line at v. j. sugumaran's machine shop has three stations. the first station can process a unit in 7 minutes. the second station has two identical machines, each of which can process a unit in 16 minutes (each unit only needs to be processed on one of the two machines). the third station can process a unit in 10 minutes. ▼ is the bottleneck station, with a bottleneck time of nothing minutes per unit (enter your response as a whole number).
