The existence of a magnetic field around a current carrying conductor can be demonstrated by placing the conductor near

Group of answer choices

a compass

a pith ball

a battery

an electroscope

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
