A 20.0m -long cable consists of a solid-inner, cylindrical, nickel core 11.0cm in diameter surrounded by a solid-outer cylindrical shell of copper 11.0cm in inside diameter and 22.0cm in outside diameter. The resistivity of nickel is 7.8*10^-8 ohm*m. What is the resistance of this cable? If we think of this cable as a single material, what is its equivalent resistivity?

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

i believe the answer is electric potential.
