Q: Because charges must have an unbroken path to follow, electric current cannot flow through a material unless it forms what? Read this paragraph and choose the correct option from the provided answers: Look at the battery and light bulb in Figure below . The light bulb works and it's connected to the battery, but it won't light. The problem is the loose wire on the left. It must be connected to the positive terminal of the battery in order for the bulb to light up. The reason? Electric current can flow through a material such as a wire only if the material forms a closed loop. Charges must have an unbroken path to follow between the positively and negatively charged parts of the voltage source, in this case, the battery. Choices: - complete loop - closed area - total loop - closed loop A:
closed loop

Q: Q: Displacement is a vector quantity, which means it has both direction and what else? Read this paragraph and choose the correct option from the provided answers: What is the difference between distance and displacement? Whereas displacement is defined by both direction and magnitude, distance is defined only by magnitude. Displacement is an example of a vector quantity. Distance is an example of a scalar quantity. A vector is any quantity with both magnitude and direction. Other examples of vectors include a velocity of 90 km/h east and a force of 500 newtons straight down. The direction of a vector in one-dimensional motion is given simply by a plus. Choices: - radiation - rate - waves - magnitude A:
A: magnitude

Question: Q: Which state of matter lacks a fixed volume, fixed shape, and consists of charged particles? Read this paragraph and choose the correct option from the provided answers: Plasma is a state of matter that lacks a fixed volume and a fixed shape and consists of charged particles called ions. Because it consists of charged particles, plasma can conduct electricity and respond to a magnetic field. Choices: - electrons - atoms - isotopes - ions A:
Answer: ions
