Connect a pair of lamps in series and you draw current from the connected battery. connect the same lamps in parallel and you drawa) the same current. b) more current. c) less current. d) sometimes more, sometimes less.

B) more current.

Explanation:

When two lamps are connected in series then we have

now let the two lamps are identical

so we have

now the total resistance of the lamps is given as

now the current in that case is given as

Now when lamps are connected in parallel

net resistance of two lamps is given as

so now we have

so we have

so now the current through the battery will be

So current will be more when two lamps are connected in parallel

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
