If the cross-section of a wire of fixed length is doubled, how does the resistance of that wire change? (this is for studying for my semester exam. i got the question wrong on one of my chapter tests so i'm trying to find out what the correct answer was) a. halved b. doubled (i know it's not this cause that was the wrong one) c. unchanged d. quadrupled

If the cross-section of a wire of fixed length is doubled,  the resistance of that wire change into doubled.We know that the total length of the wires will affect the amount of resistance.  The longer the wire, the more resistance that there will be so the answer is doubled.

This is what i found on google “kinetic energy. energy is transferred from one object to another when a reaction takes place. energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few. this energy would be in the form of motion, with the person lifting the blue ball to a higher level.” i hope this you
