Q: Speed is an important aspect of motion. It is a measure of how fast or slow something moves. To determine speed you must know two things. First, you must know how far something travels. Second, you need to know how long it takes to travel that far. Speed can be calculated using this formula: speed = distance time A familiar example is the speed of a car. In the U.S., this is usually expressed in miles per hour. Think about a trip you and your family made in the car. Maybe the trip covered 120 miles and it took 3 hours. What was the cars speed? speed = 120 mi = 40 mi/h 3h The speed of a car may also be expressed in kilometers per hour (km/h). The SI unit for speed is meters per second (m/s). This is the unit of measure a scientist would use. <sep>What is speed?<sep>When something moves

A: No

Q: At length, as I entered the pass, the huge rocks began to close around in all their wild, mysterious impressiveness, when suddenly, as I was gazing eagerly about me, a drove of gray hairy beings came in sight, lumbering toward me with a kind of boneless, wallowing motion like bears.  I never turn back, though often so inclined, and in this particular instance, amid such surroundings, everything seemed singularly unfavorable for the calm acceptance of so grim a company.  Suppressing my fears, I soon discovered that although as hairy as bears and as crooked as summit pines, the strange creatures were sufficiently erect to belong to our own species.  They proved to be nothing more formidable than Mono Indians dressed in the skins of sage-rabbits.  Both the men and the women begged persistently for whisky and tobacco, and seemed so accustomed to denials that I found it impossible to convince them that I had none to give.  Excepting the names of these two products of civilization, they seemed to understand not a word of English; but I afterward learned that they were on their way to Yosemite Valley to feast awhile on trout and procure a load of acorns to carry back through the pass to their huts on the shore of Mono Lake. <sep>What color were the rabbit skins?<sep>Sage rabbits

A: Yes

Q: The Reconquest: The aim of the Crusades in Spain was the eviction of the Muslims. After the recovery of Jerusalem in 1099, it took four hundred years of sieges and battles, treaties, betrayals, and yet more battles, before Christian kings and warlords succeeded in subduing the Moors. On 10 September 1229, a Catalan army led by King Jaume I of Aragón and Catalunya took the Mallorcan shore near the present-day resort of Santa Ponça. The defenders retreated inside the walls of Palma, but on the last day of 1229 the city fell, and pockets of resistance throughout the island were also defeated. Jaume I proved to be an enlightened ruler who profited from the talents of the Moors — converted by force to Christianity — as well as of the island's large Jewish and Genoese trading communities. Mallorca prospered. The Moors on Menorca speedily agreed to pay an annual tribute to Aragón and were left in peace. The island's tranquility lasted until 1287, when Alfonso III of Aragón, smarting over a series of humiliations at the hands of his nobles, found a pretext for invasion. The Moors were defeated and expelled or killed. In contrast to Mallorca, Menorca's economy was devastated for decades. Jaume I died after reigning in Aragón for six decades, but he made the cardinal error of dividing between his sons the lands he had fought for so long to unite. At first this resulted in an Independent Kingdom of Mallorca, under Jaume II, followed by Sanç and Jaume III. But family rivalry triggered the overthrow of Jaume III by his cousin Pedro IV, who then seized the Balearics for Aragón. Attempting a comeback, Jaume was killed in battle near Llucmajor in 1349. A newly unified Christian Spain under the Catholic Monarchs, Ferdinand and Isabella, completed the Reconquest, defeating the only Moorish enclave left on the Iberian peninsula, Granada, in 1492. However, the centralized kingdom failed to incorporate the Balearics politically or economically. <sep>What was the purpose of the many battles in  Spain and how long did it take<sep>The purpose of the battle was to rid of the muslims which took about 400 years

A:
Yes
