Explanation The movement of free electrons is defined as electric current , which is the flow of electrons through a conductor, such as a wire. Electric charge refers to the property of matter, electric field is the force that surrounds charged particles , and electric potential is the potential energy per unit charge.

Explanation Nuclear fusion is the process by which atomic nuclei combine to form a heavier nucleus, releasing vast amounts of energy in the process. In the case of stars, nuclear fusion occurs when hydrogen atoms fuse together to form helium, releasing energy in the form of light and heat. Explanation Stars are massive, luminous balls of gas that are primarily composed of: Hydrogen (about 70%) Helium (about 28%) Explanation Resistance (C) is the opposition to the flow of electric current. It is measured in ohms (Ω). Explanation In most businesses and homes , electrical circuits are connected in parallel to ensure that : Each device receives the same voltage If one device fails or is turned off, others remain operational The entire circuit doesn't fail if one device is disconnected Explanation When two bulbs are connected in a series circuit and one bulb blows, the entire circuit is interrupted, and the other bulb will also stop glowing , i.e., also blow (blast). This is because there is no longer a complete path for current to flow through the circuit. Explanation A series circuit is a circuit that provides only one path for the current to flow. If one component is removed or fails , the entire circuit is interrupted. Explanation The electrons that have been knocked out of the outermost shell of an atom are free electrons , which are able to move freely and conduct electricity. Explanation The movement of free electrons is defined as electric current , which is the flow of electrons through a conductor, such as a wire. Electric charge refers to the property of matter, electric field is the force that surrounds charged particles , and electric potential is the potential energy per unit charge. Explanation Dolphins have a wide audible range that is adapted to their aquatic environment. They can hear sounds in the range of 20 Hz to 120,000 Hz , which is far beyond the human audible range. Explanation Cats have a unique audible range that is adapted to their hunting and communication needs. They can hear sounds in the range of 45 Hz to 64,000 Hz , which is wider than humans and dogs.
