Sound waves are mechanical waves. They can travel only through matter. They cannot travel through empty space. This was demonstrated in the 1600s by a scientist named Robert Boyle. Boyle placed a ticking clock in a sealed glass jar. The clock could be heard ticking through the air and glass of the jar. Then Boyle pumped the air out of the jar. The clock was still running, but the ticking could not be heard. Thats because the sound couldnt travel without air particles to transfer the sound energy. Is there any other place where sound cannot be heard? Here is a hint: is there any other place that does not have air molecules? Thats right, in space sound cannot be transferred. So can astronauts hear each other? Yes, they can, because they are in enclosed space stations or pressurized suits.In both cases, they are surrounded by air molecules. If they left their space ship and did not use their electronics, they would not be able to hear each other. Next time you watch a science fiction movie, think about this factoid. When spaceships are destroyed by hostile alien beings, there would be no sound heard. Sound waves can travel through many kinds of matter.

Question: "What can sound waves move through?"

Response: "matter."

A: yes

With a budget of $329 million, LSC provides civil legal assistance to low-income people in every county in America, Kleiman said. NLAP was created in 1968. A decade later, the agency used a $50,000 LSC grant to buy a building at 438 King St. in Charleston and $33,000 to buy a building at 201 King St. in Georgetown, according to Erlenborn's letter to Kaynard. In 1980, NLAP used $63,000 in LSC funds to buy property at 607 Main St. in Conway, the letter said. On Nov. 14, 2001, NLAP transferred title of the King Street building in Charleston to the Charleston County Bar Association, according to county property records. The local bar paid $5 for the building, which sits between a redeveloped office building and an antique shop. The local bar said it would maintain the building for "legal services to indigent residents of Charleston County and coastal South Carolina," the records said. The King Street building appears to be vacant. Notices at the entrance direct visitors to the equal justice center on West Montague Avenue in North Charleston. E. Douglas Pratt-Thomas, president of the local bar, was not available for comment. Charleston County has not appraised the King Street property because it is tax-exempt. But Randall Goldman, managing partner of Patrick Properties, which owns buildings from 440 to 456 King St., said he estimates 438 King St. would sell for between $700,000 and $900,000. "That building, which was purchased solely with federal legal aid dollars, should be used to provide legal services for poor people in South Carolina," Kleiman said. LSC wants the title to go to the equal justice center in Charleston or "we want 100 percent of the proceeds from the sale of the building to stay in Charleston. We are not contemplating taking that money out of South Carolina," he said. Kleiman said if the neighborhood legal program in Charleston "had honored their obligation, this would not be an issue."

Question: "The local bar in Charleston County maintained which building of the NLAP in exchange for "legal services" to certain residences?"

Response: "The NCAP Building"

A: no

Tom plays pool in a deserted pool hall , pocketing two balls by lowdown means and then wakes Jerry up by shooting the 10-ball into the pocket where he is sleeping . Jerry awakes just in time to avoid the 10-ball and is carried out to the ball return , where the 10 and the 13 smash the mouse between each other . Jerry is mad and walks up through the pocket , first sees nothing , but after a few steps back to the pocket , he spots Tom perched behind it . Jerry tries to jump into another corner pocket , but Tom aims a cue ball with so much force that it roll's into the pocket , and spins back out of it and it rolls Jerry backwards to Tom , who has made a ramp with his cue stick for the mouse to slide up . Jerry stops at the top of the stick and is then blown down by Tom , who then shoots a stream of balls to make the mouse flat . The whole train rebounds back towards the cat and the balls stack up at Tom's end of the table . Tom shoots all the balls in succession with his cue , and then tries to shoot Jerry , but the mouse hangs onto the cue tip . The cat , as if he were saying '' Have it your way '' , chalks up and shoots the 8-ball using Jerry . The mouse drops off the cue tip and then is upended by the 8-ball rolling in circles , and Tom forces Jerry to jump through the ball rack as if he were a circus performer . Tom then sets it on fire to add an additional level of torment , and when Jerry accomplishes this with poise , Tom discards the flaming rack and shoots the 8-ball across the table and back .

Question: "Why did the mouse drop off the cue tip?"

Response: "He didnt want to hold it anymore"

A:
yes
