Acircuit contains a 12 volt battery and two 3 ohm bulbs in series. calculate the current

If there are two bulbs in series, and each bulb has

                                                   resistance = 3 ohms,

then their total resistance in series is 6 ohms. 

When the series pair of bulbs is connected across the terminals
of the battery, the current through the circuit is

 Current = (voltage) / (resistance) 

               =  (12 volts) / (6 ohms)  =  2 amperes

This is what i found on google “according to the collision theory, the following criteria must be met in order for a chemical reaction to occur: molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. molecules must collide with the proper orientation.” i hope this information you.

Kinetic energy = 1/2mv^2. since the mass is constant we can form a ratio of it's kinetic energy at 60 divided by that at 30 to see ke(60)/ke(30) = +(60^2)/30^2). this may be said to 300% increase.
