While buying a hot plate you notice the resistance of the hot plate is 25.0 . when connected to a 120. v source, how much current will the hot plate carry? remember to identify all data (givens and unknowns), list equations?

The basic relationship between voltage, resistance and current of an electrical device is given by Ohm's law:

where
V is the voltage
I is the current
R is the resistance

The hot plate in our problem is connected to a source of V=120 V and it has a resistance of , therefore we can rearrange the previous equation to calculate the current through the device:

The question is incomplete, the complete question is;

Rutherford tracked the motion of tiny, positively charged particles shot through a thin sheet of gold foil. Some particles traveled in a straight line and some were deflected at different angles. Which statement best describes what Rutherford concluded from the motion of the particles? Some particles traveled through empty spaces between atoms and some particles were deflected by electrons. Some particles traveled through empty parts of the atom and some particles were deflected by electrons. Some particles traveled through empty spaces between atoms and some particles were deflected by small areas of high-density positive charge in atoms. Some particles traveled through empty parts of the atom and some particles were deflected by small areas of high-density positive charge in atoms.

Some particles traveled through empty parts of the atom and some particles were deflected by small areas of high-density positive charge in atoms.

Explanation:

Rutherford first proposed the nuclear model of the atom after his landmark experiment.

In this experiment, alpha particles from a source was focused on a thin gold foil. Some of the particles passed through empty spaces within the atom but were deflected at different angles by a small area of high-density positive charge within an atom which Rutherford later called the atomic nucleus.

Hence the answer above.
