C. Positive
If an electric circuit has zero Ampere (0A) of current running through it, then the voltage must be zero.
Ohm's law states that the current flowing through an electric circuit is directly proportional to the voltage (potential difference) applied across the two terminals of an electric circuit and inversely proportional to the resistance in the electric circuit, at a constant temperature.
This ultimately implies that, the value of voltage (potential difference) is highly dependent on the value of the current running through an electric circuit.
Mathematically, Ohm's law is given by this formula;
Where:
In conclusion, if an electric circuit has zero Ampere (0A) of current running through it, then the voltage must be zero.

Answer:
1. Option C: Voltage
2. Option B: Zero
Explanation:
According to Ohm's law, the current in a circuit is directly proportional to the voltage. This means, when there is potential difference across the two ends of a circuit, then only current flows.
I ∝ V
If the given circuit has 0 A current, it means that either potential is zero or resistance is infinite. Practically, we cannot have infinite resistance. This means that the voltage must be zero.
Rutherford's experiment conclude that: atoms are not solid, atoms are hollow and most of the space is vacuum and the positive charge in an atom is not spread evenly .
Rutherford's observations lead him to draw the following conclusions:

Rutherford's model of the atom (ESAAQ) Rutherford carried out some experiments which led to a change in ideas around the atom. His new model described the atom as a tiny, dense, positively charged core called a nucleus surrounded by lighter, negatively charged electrons.
Answer:
B) carry on further discussion, using many trials if experimentation is needed.
Explanation:
To know if the procedure is the best, the hypotheses raised there must be verified in many ways, choosing experiments that do not provide us with ambiguous or incomplete results. It is very important that any other person can repeat it, since a scientific discovery is not valid until another scientist has replicated it.
Answer:
B
Explanation:
Answer:
An atom that loses a electron is called a cation and has an overall positive charge.
