question:
The motion of an object can be represented by a position-time graph like Graph 1 in the Figure 1.1. In this type of graph, the y-axis represents position relative to the starting point, and the x-axis represents time. A position-time graph shows how far an object has traveled from its starting position at any given time since it started moving. Q: In the Figure 1.1, what distance has the object traveled from the starting point by the time 5 seconds have elapsed? A: The object has traveled a distance of 50 meters. In a position-time graph, the velocity of the moving object is represented by the slope, or steepness, of the graph line. If the graph line is horizontal, like the line after time = 5 seconds in Graph 2 in the Figure 1.2, then the slope is zero and so is the velocity. The position of the object is not changing. The steeper the line is, the greater the slope of the line is and the faster the objects motion is changing. Its easy to calculate the average velocity of a moving object from a position-time graph. Average velocity equals the change in position (represented by d) divided by the corresponding change in time (represented by t): velocity = d t For example, in Graph 2 in the Figure 1.2, the average velocity between 0 seconds and 5 seconds is: d t 25 m 0 m = 5 s0 s 25 m = 5s = 5 m/s velocity =
answer:
the slope of a position-time graph can be used to find the moving objects


question:
Ashley and Chris work in the same department designing postcards. Chris had a college degree in art and deeply felt that the degree of his designs was excellent. His last postcard showed the depth of a desert's beauty and delights. "It's just a picture of the desert," Ashley said. "Not deep at all." "Some people desire seeing beauty," Chris replied. "Mine delivers that". Ashley laughed and said, "well, that depends on what you think beauty is." Days later, someone delivered a letter to Ashley. The letter said, "You are worthy of the bad things that will come your way. You will know the taste of defeat, and I will destroy you." Ashley suddenly felt very cold. It was as if the room temperature had dropped 30 degrees. "Who would do such a shocking deed?" she wondered. "I will not let a simple letter defeat me." Just then, Chris came into the room and offered Ashley a piece of his sandwich. "Try some," he smiled widely. "It's delicious." "Are you trying to poison me?" Ashley asked. Chris's answer was delayed from confusion. "What's your problem?" he asked. The next day, Ashley brought a bat to use to defend herself. When Chris saw her bat, he joked, "Defend and win one for the team." Ashley took no notice of him. She spent the whole day reading self-defending books and placed her work on delay. "You can't delay your work. Our job demands us to do our work on time," Chris said. "We must meet the demands of our job." "You're not the boss," Ashley replied. "Don't make demands of me." Because Ashley failed to do her work, she was fired. Chris glanced at Ashley's empty desk and smiled.
answer:
What kind of work did Chris and Ashley do?


question:
In the Caucasus region of Russia, nearly 50 out of every 100,000 people live to celebrate their 100th birthday, and many don't stop at 100! By comparison, in America only 3 people in 100,000 reach 100. But these Russian old people aren't alone. The Pakistanis, who live high in the Himalaya Mountains, and the Ecuadorans of the Andes Mountains seem to share the secret of long life, too. These people remain healthy in body and spirit despite the passage of time. While many older persons in industrial societies become weak and ill in their 60s and 70s, some Caucasians aged 100 to 140, work in the fields beside their great-great-grandchildren. Even the idea of aging is foreign to them. When asked "at what age does youth end?"most of these old people had no answer. Several replied, "Well, perhaps at age 80." What accounts for this ability to survive to such old age, and to survive so well?First of all, hard physical work is a way of life for all of these long-lived people. They begin their long days of physical labor as children and never seem to stop. For example, Mr . Rustam Mamedov is 142 years of age. His wife is 116 years old. They have been married for 90 years. Mr. Mamedov has no intention of retiring from his life as a farmer. "Why?What else would I do?"he asks. All these people get healthful rewards from the environment in which they work. They all come from mountainous regions. They live and work at elevations of 1,660 to 1,000 meters above sea level. The air has less oxygen and is pollution-free. This reduced-oxygen environment makes the heart and blood vessel system stronger. Another factor that may contribute to the good health of these people is their isolation. To a great extent, they are separated from the pressures and worries of industrial society. Inherited factors also play some role. Most of the longest-lived people had parents and grandparents who also reached very old ages. Good family genes may, therefore, be one factor in living longer.
answer:

What is the main way of life for all of these long-lived people?
