When Rutherford ran his gold foil experiment, he expected to see results like those in the Plum Pudding Atom simulation. Instead, his experimental results were closer to those seen in the Rutherford Atom simulation. Why can't the plum pudding model of the atom explain Rutherford's experimental results? Since some alpha particles were deflected, the atom must contain a small region with a strong electric charge. Since most of the alpha particles were not deflected, the atom's positive charges must be spread thinly across a large region. Since some of the alpha particles were deflected, the atom's negative charges must not be attracted to the alpha particles. Since most of the alpha particles were not deflected, the atom's negative charges must exist in a thin cloud around the atom.

Question 2 (2 points) Why is Ohm's Law relevant? Ohms law is extremely important to the world of electrical circuits and components but is not suitable for every electrical circuit and application. There are certain requirements that a circuit and electrical component should meet to ensure that Ohms law is applicable. Ohms law can be used to calculate the required value of Voltage or components within a circuit, it can also work out the amount of current that flows in an electrical circuit when resistors can be measured across electrical components such as voltage. Ohm's Law is not relevant Ohm's Law is only used in a DC circuit.
