Answer:
Alternating; direct.
Explanation:
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
Alternating currents are most often used in the wiring of new buildings and homes, while direct currents are the type stored in batteries and fuel cells.
Basically, the direction of an alternating current changes periodically.
The acceleration on surface of moon =1.67m/s^2
Weight =mass ×acceleration
=7×1.67
=11.69N
kinematics can be defined as a sub-discipline in physics aimed at understanding the motion of objects without considering the forces that move them.
- Classical mechanics refers to a physical theory that describes the motion of objects.
- Kinematics can be considered a branch of classical mechanics that studies the motion of objects but without considering the forces that move them.
- Kinematics describes the motion of objects and systems by using different types of information such as diagrams, numbers, equations and/or graphs.
In conclusion, kinematics is a sub-discipline in physics aimed at understanding the motion of objects without considering the forces that move them.

Answer:
No chemical bonds are broken or formed in melting butter, so it is not a chemical change. The melting process is only a physical change, the change of state from solid to liquid.
