Question
please answer and submit.
Aliens from the planet Tehar with strange powers visit the planet Earth and double every linear dimension of every object on the surface of the planet. Does the electrical cord from the wall socket to your floor lamp now have more resistance, less resistance or the same resistance as it did before? Prove your answer and determine by what factor the resistance changes, if it changes at all. Does the light bulb filament glow more brightly, less brightly or the same as before? The electric field inside a charged conductor in equilibrium is: Dependent upon the amount of charge on the conductor. 0. Perpendicular to a line drawn from the center of the conductor to its surface (i.e. a radius vector). The electric potential inside a charged conductor in equilibrium is: Constant everywhere.0. Dependent upon the amount of charge on the conductor.(2 pt) Are the headlights of your car wired in series or parallel? How do you know, other than looking under the hood or checking a wiring diagram?Explanation / Answer
1. the resistance of a wire is directly proportional to its length therefore doubling the length will double the resistance of the wire. However when the length of the wire is doubled, its cross-sectional area is halved. ( I'm assuming the volume of the wire remains constant and of course that the wire is a cylinder.) As resistance is inversely proportional to the cross-sectional area, halving the area leads to doubling the resistance. The combined effect of doubling the length and halving the cross-sectional area is that the original resistance of the wire has been quadrupled.
if the resistance is increased the light bulb wil glow more brightly because P=V^2/R so power is decreased so more glow.
2. zero
3. constant
4. they are in parallel because they are connected to the same potential...and even if one head light got damaged the other light goes on working this shows that they are not in series...
