The apparatus used to capture wind is called a windmill.
If there is no slipping or skidding going on, then for each revolution, the tire rolls along the ground a distance equal to the tire's circumference.
Circumference of the tire = 2 · π · Radius .
During the same revolution, the small stone stuck in the tread travels in a big semicircular arc that's <em>(2 · π · r)</em> long. (roughly 6.28r)
-- Bob covered a distance of (32m + 45m) = 77 meters.
-- His displacement is the straight-line distance and direction
from his starting point to his ending point.
The straight-line distance is
D = √(32² + 45²)
D = √(1,024 + 2,025)
D = √3,049 = 55.22 meters
The direction is the angle whose tangent is (32/45) south of east.
tan⁻¹(32/45) = tan⁻¹(0.7111...) = 35.42° south of east.
Answer:
C) Rear
Explanation:
For better understanding, let me explain first what actually is the Whiplash injury. It usually occurs in the accidents related to vehicles and cause injury in the neck. It happens because of the very forceful, rapid movement of head and neck forward and backward. So unfortunately if there is a sudden impact of car from the rear and if it's velocity changes from 10 to 15 km/h (as the studies show) it will results in the whiplash injuries. So the correct option here is the third one "<em>rear</em>".
Answer:
Testing
Explanation:
Ancient Greek philosophers lived with the ideology to simply contemplate life. This means that their whole life revolved around thinking and questioning everything. This would include creative thinking, because they would sometimes come up with theories which require creativeness. They would often debate with their friends as to why their theory should be accepted or what their opinions were on the matter. More often than not, they argued a lot, and many philosophers went against some powerful people in the community and some were even sentenced to death.
The main process they didn't/couldn't do was the testing. They could never test certain theories because they did not have the means to.
