Magnetism is the ability of a material to be attracted by a magnet. It also include the ability for some material to act like a magnet. No doubt youve handled refrigerator magnets. You can see some in Figure 1.28. You probably know they stick to a metal refrigerator. This is what holds your homework up. Maybe your little sisters drawings are hung on the fridge in this manner. Do magnets stick to all materials? Of course not. You have probably checked and they do not stick to other surfaces. They do not stick to wooden doors or glass windows. Wood and glass are not attracted to a magnet. Obviously, only certain materials are attracted to magnets.

Question: "Give examples of materials to which magnets stick to and do not stick to."

Answer: "Wood"

Response: no

(CNN) -- We'll let you finish, but The Muppets have the best Instagram account of all time. The feed was launched just over a month ago as part of a promotional push for their upcoming movie, "Muppets Most Wanted." But in between quippy posters and ads for the film, which is a sequel to 2011's blockbuster "The Muppets" with Jason Segel, there are ingenious "selfies" from the Muppets crew. In fact, the first post was a coy snapshot from Kermit, Miss Piggy and Gonzo, with a filter in full effect: And the selfies grew more adorable -- and more hilarious -- from there: We now have evidence of the time Animal burst in on Beaker in the bathroom. And we know what Gonzo does after a hard day of stunts. "Gonzo treated himself to a massage today to try to work out all of his stuntman kinks. Even weirdos need pampering. #bougielife #yolo," reads the caption to this pic: The Muppets' curmudgeonly yet lovable critics, Statler and Waldorf, are still trying to get the hang of taking the perfect selfie -- "This is the fanciest calculator we've ever seen!" they were heard saying when the photo was taken -- while Rowlf is clearly a selfie king. From the Swedish Chef to Miss Piggy's evil alter ego, everyone has gotten in on the first-person photo sessions. The only people noticeably missing from the account are the Muppets' human co-stars in "Muppets Most Wanted," like Tina Fey, Ty Burrell and Ricky Gervais. As with the first "Muppets" film, which also starred Amy Adams, Chris Cooper and Rashida Jones, the "Muppets" sequel has plenty of human star power. In addition to Fey and Gervais, "Muppets Most Wanted" also has appearances from Tom Hiddleston, Salma Hayek, Stanley Tucci and Lady Gaga.

Question: "Who is considered a weirdo in the cast of "Muppets Most Wanted"?"

Answer: "Gonzo"

Response: yes

(CNN) -- Britain's Chris Froome won the 17th stage of the Tour de France on Wednesday to strengthen his grip on the yellow jersey. Froome completed Wednesday's 32-kilometer time trial in 51 minutes 33 seconds, nine seconds ahead of Spain's Alberto Contador with his compatriot Joaquim Rodriguez Oliver finishing a further second behind in third. "I couldn't believe it when I got over the line and saw I had the fastest time," Froome said after his third stage win of this year's tour. "I went into today thinking I was going to try and limit my losses, thinking about the days to come now. So to go through the finish line with the fastest time, I really didn't see that coming." On mountainous terrain along a frequently twisting route most of the riders opted for their traditional road bikes over the more aerodynamic machines used in time trials. But Froome opted to use both on the stage, switching to a time trial model for the final 12-kilometer descent. The swap proved decisive as the Briton clawed back a 20-second advantage Contador had built up earlier in the stage. The Spaniard now moves up to second overall, four minutes 34 seconds behind Froome with just four stages remaining. Contador's Saxo-Tinkoff teammate Roman Kreuziger is now third and trails Froome by four minutes and 51 seconds. Thursday sees the riders tackle the gruelling 172.5-kilometer 18th stage which concludes with a double ascent of Alpe d'Huez over the last 60 kilometers.

Question: "How long did Fromme bike on the 17th stage before the final descent?"

Answer: "20km"

Response:
yes
