A 12-volt battery is connected to two light bulbs, as drawn in
Figure 1. Light bulb 1 has resistance 3 ohms, while light bulb 2
has resistance 6 ohms. The battery has essentially no internal
resistance, and all the wires are essentially resistanceless,
too.
When a light bulb is unscrewed, no current flows through that
branch of the circuit. For instance, if light bulb 2 is unscrewed,
current flows only around the lower loop of the circuit, which
consists of...

QUESTION 1 A battery operated car of mass 1,225 kilograms uses a 10.4 volt system. What is the charge in coulombs the batteries must be able to move in order to accelerate the care from rest to 22.7 meters per second? Your final answer must be in scientific notation. Remember that 333 = 3.33e2. All you need to do is give me the number here as I have already given you the units and this silly program cannot handle units....
