Re: physics ?

No NET velocity change if traveling through a vacuum. Even vapour molecules will continue at the same speed as the ice cube they came from; plus or minus the little velocity they got going to gas state. Resulting in a wet ice cube with a cloud. The cloud would get larger due to random collisions and...

Re: telephone light

If you connect inside the phone, right across the ringer, you only need the Ne lamp and a resistor. (Because the phone already the capacitor in series with the ringer.)<p>On the other hand, to connect across the line you will need a capacitor too. Otherwise, once the ringing voltage strikes the Ne l...
