Final answer:
If the free red alligator clip is connected to the free terminal of the battery, none of the bulbs will glow.
Step-by-step explanation:
If you connect the free red alligator clip to the free terminal of the battery, none of the bulbs will glow. To understand this, we need to consider the circuit configuration. In order for a lightbulb to glow, it needs to be connected in a closed circuit where the current can flow through it. However, in this case, if the alligator clip is connected to the free terminal of the battery, there is no complete pathway for the current to flow through any of the bulbs. Therefore, none of the bulbs will glow. The radius from the distance of separation between charges in electricity, you need to have information about the charges and their electric fields. The electric field is a measure of the force experienced by a positive test charge at a point in space. The electric field formula is given by E = kQ/r^2, where E is the electric field magnitude, k is the electrostatic constant, Q is the charge, and r is the distance between the charges.
