3. A marble with 0.02 kg mass is moving towards right with a velocity of 20 cmys, makes a head on collision with a second marble with a mass of 0.02 kg which is moving towards left with a velocity of 10 cms. After collision the 1st marble moving towards left with a velocity of 10 CM/s, and what is the velocity of 2nd marble after collision?
10 cm/s Left
10 cm/s Right
20 cm/s Right
30 cm/s Right

answer: the answer is a

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

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
