Suppose an electrical wire is replaced with one having every linear dimension doubled (i. e., the length and radius have twice their original values). How is the resistance of the wire affected?

a. The wire has the same resistance as before.

b. The wire has more resistance than before.

c. The wire has less resistance than before.

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
