Magnets are able to place a force on certain materials. This force is called a magnetic force. The force a magnet exerts is a little different from the forces you may normally think about. You exert a force on a book when you lift it. You also exert a force on the pedals of your bicycle. In both those cases, those forces cause a change. The change you see in both these cases is called motion. Magnets, too, can produce change. They can produce motion just like you do. Unlike you, magnets do not have to touch something to exert a force. A magnetic force is exerted over a distance. Thats right, a magnet can push or pull certain items without ever touching them. Thats how the maglev train works. Do you know another type of force that does not require objects to touch? These forces are known as non-contact forces. Another type of non-contact force you may be familiar with is gravity. Gravity too can cause changes in motion. Gravity holds our moon in orbit without touching it.

Question: "What are non contact forces?"

Answer: "Non-contact forces are gravity and maglev train"

Response: no

I'm here to tell you the story of a robot named Carl. He came from a far away land known as Factory. Carl was sad because he was missing a part called a tire. He also needed a sun gatherer. But, the tire was more important. Once Carl got all these parts he could travel to his new home in the nation of Lab and the city of Office. It was a tricky thing to get there with missing parts. Just as he had given up hope Carl got a message from Mr. X saying the new parts were ready to be delivered. This made the robot very happy. The parts arrived a few days later and Carl put them in with 2 days of work. After this Carl began to travel the last bit of his goal to get to his new job. After this Carl took 10 days to get to Lab.

Question: "Which parts is Carl the robot missing?"

Answer: "All the parts"

Hotel California My first thought: I was going crazy. Twenty-four hours of silence (vacuum, remember); was I hallucinating noises now? I heard it again. It was a fine bell, reminiscent of ancient stone churches and the towering cathedrals I'd seen in documentaries. And accompanying the bell, I saw a light. Now, there were two things here that made ridiculously small amounts of sense. First, the whole in-a-vacuum why's-there-a-bell thing. Second, I was floating in the dark remnants of my broken ship, and any conceivable light sources were not within view; starlight is a distinctly different color and significantly less bright. These signals were the heralds of my saviors. The first words they said to me meant nothing. I wasn't listening; I didn't care; I was going to live; I was going to keep breathing. Next to those, nothing else mattered. The recycled air tasted sweet in my mouth, and all thoughts that crossed my mind were cheap metaphors about life-giving substances and how breathing was like sex, only better. (I reserved the right to revise this opinion later.) When I was done mentally exclaiming over my impossible rescue, I looked around. The ship, it was odd and old, either so outdated or so heavily modified that I couldn't tell what make it was, and somehow, the crew standing around me fit the same description, a singularly atypical amalgamation of folk. And me, I guess I was one more piece in their puzzle. I was one more scrap to weld onto the rest, one more stranded survivor who was found. I was now one of them.

Question: "Where did the sound and the light come from?"

Answer: "The weather"

Response:
no
