Answer:
Dalton's atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. while all atoms of an element were indentical , different element had atoms of differing size and mass.

The mechanical energy of the system at any point in time can be in the form of kinetic energy, potential energy, and elastic energy. These all are interconvertible, hence mechanical energy is conserved.
The term mechanical energy accounts for the total energy by the virtue of position as well as the motion of an object.
When an object is dropped from a certain height, then the mechanical energy of the object at any instant is given as the sum of kinetic energy and potential energy. The expression is given as,
ME = KE + PE
But at some point in time, the potential energy can be in the form of elastic energy as well. This energy is known as spring potential energy. Hence, the mechanical energy is conserved in a system at any point considering the forms like kinetic energy, potential energy, and elastic energy.
Thus, we can conclude that the mechanical energy of the system at any point in time can be in the form of kinetic energy, potential energy, and elastic energy. These all are interconvertible, hence mechanical energy is conserved.

A.
Electrical energy turns the rod. This energizes the coil. The magnetized coil generates an electric current. The electric current goes through the wires to power the lightbulb.
B.
Mechanical energy turns the rod. This electrifies the coil. The electrified coil generates a magnetic field. The magnetic field goes through the wires as electricity to power the lightbulb.
C.
Mechanical energy turns the rod. This magnetizes the coil. The magnetized coil generates an electric current. The electric current goes through the wires to power the lightbulb.
D.
The magnetic energy in the coil turns the rod. The rod generates an electric current. The electric current goes through the wires to power the lightbulb.
The magnetic force on the wire will be directed to the east.
The direction of the magnetic force on the long wire carrying a current toward the north in a magnetic field directed vertically downward would be to the east.
This is because of the right-hand rule, where if you point your right thumb in the direction of the current and your fingers in the direction of the magnetic field, the resulting force would be perpendicular to both, pointing to the east in this case.
When a long wire carries a current toward the north in a magnetic field that is directed vertically downward, you can determine the direction of the magnetic force on the wire using the right-hand rule.
Step 1: Point your right thumb in the direction of the current (north).
Step 2: Curl your fingers in the direction of the magnetic field (downward).
Step 3: The direction of the force on the wire will be the direction your palm is facing.
Following these steps, the magnetic force on the wire will be directed to the east.

Answer:
The sentence that describes the movement of matter and energy in the water cycle is:
C. Energy from sunlight warms the ocean surface and causes water to evaporate.
Explanation:
In the water cycle, energy from sunlight plays a crucial role in causing water to evaporate from the ocean surface. This evaporation process occurs when the sun's energy heats up the water, increasing its temperature. As a result, the water molecules gain enough energy to break free from the liquid state and transform into water vapor, which rises into the atmosphere. This step represents the movement of both matter (water) and energy (sunlight) in the water cycle.
