Acertain 1.5-v battery (whose original mass is about 0.425 kg) has a capacity of 4.5 ah. about how much lighter is this battery when it is discharged than when it is full? it has the same number of electrons when discharged as it does when it is full.

current flows in a wire

find the sum of the two horizontal vectors and the sum of the two vertical vectors

isoceles right angled triangle

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

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

= final temperature = ?

using the equation
