Ques: Answer the following question given this paragraph: When current flows in just one direction, it is called direct current (DC) . The diagram below shows how direct current flows through a simple circuit. An example of direct current is the current that flows through a battery-powered flashlight. In addition to batteries, solar cells and fuel cells can also provide direct current. Q: What kind of current flows in just one direction? Choices: - physical current - slow current - Alternating current - direct current A:
Ans: direct current

Ques:Answer the following question given this paragraph: A: With greater reflection off the ionosphere, AM waves can travel even farther at night than they can during the day. Radio receivers can often pick up radio broadcasts at night from cities that are hundreds of miles away. Q: Greater reflection off what atmospheric layer allows am radio waves to travel even farther at night than they can during the day? Choices: - stratosphere - exosphere - troposphere - ionosphere A:

Ans:ionosphere
Question: Answer the following question given this paragraph: Most waves approach the shore at an angle. The part of the wave that is nearer the shore reaches shallow water sooner than the part that is farther out. The shallow part of the wave "feels" the bottom first. This slows down the inshore part of the wave and makes the wave "bend. " This bending is called refraction . Q: What three characteristics do waves have? Choices: - structure , refraction and deflection - theory , refraction and deflection - spin, refraction, and deflection - reflection, refraction and deflection A:
Answer:
reflection, refraction and deflection
