Sitting comfortably in your soft chair, reading the book in your lap or listening to your mp3 player with buds stuffed in your ears. Your eyes are heavy, hard to hold them open, and the rest of you is getting drowsy. From time to time, maybe every few minutes, your soft chair rocks gently side to side a few times, then settles down. It's getting dark outside, and you are getting sooo sleeepy . . .
Your soft chair is in Row-27 of the passenger airliner you're riding in. The airplane is cruising 35,000 feet above the ground, and relative to the people on the ground, you, the plane, and your book are all traveling at almost 500 miles per hour. ______________________________________
You're relaxing on your beach chair, in your back yard, working on your tan on a warm sunny day. Just like on the airplane last week, you're warm and comfy, and getting drowsy.
Relative to the Earth's axis, you're moving at around 700 miles per hour, but the direction of your motion is only changing by about 1 degree each 4 minutes.
Relative to the sun's axis, you're moving at almost 67,000 miles per hour, but the direction of your motion is only changing by about 1 degree each day.
Atmospheric pressure is caused by the weight of the atmosphere pushing down on itself and on the surface below it. Pressure is defined as the force acting on an object divided by the area upon witch the force is acting.
A basketball sitting on a horizontal surface will experience static friction which prevents it from moving. Static friction is higher than when the ball and surface are in motion relative to each other. Objects that are resting on horizontal surface experience static friction which gives way to kinetic friction where the two objects, the surface and the object at rest, move relative to each other. The statement in the question is incorrect.
The length of path according to the tourist is 8111.10 meters.
Explanation:
It is given that,
Speed of tourist, v = 1.3 m/s
Path length, L₀ = 9 km = 9000 m
If the speed of light in a vacuum were 3.0 m/s. We need to find the length of path according to the tourist. Let it is L. It is a case of length contraction.
So,
L = 8111.10 m
So, the length of path according to the tourist is 8111.10 meters. Hence, this is the required solution.
