Should be B I took the same
Answer:
1) A:1, B:1, C:1
2) A:1, B:1, C:1
3) B:1, C:2, A:3
Explanation:
1)
a = , where V - linear speed.
R - radius of ferris wheel.
These values are constant, so at any position centripetal acceleration will be the same.
2)
F = ma = , where a - centripetal acceleration.
V - linear speed.
R - radius of ferris wheel.
These values are constant, so at any position centripetal force will be the same.
3)
So, at bottom point normal force is maximume, at top point normal force is minimum.
B:1, C:2, A:3 (bottom: Greatest, midheight: Second greatest, top: Third greatest)
Answer:
So, if the car slips in mud it will either skid or slide depending on the size of the mud puddle.
Does this work?
Answer:
It is easy to imagine representing a narrow beam of light by a collection of parallel arrows—a bundle of rays. As the beam of light moves from one medium to another, reflects off surfaces, disperses, or comes to a focus, the bundle of rays traces the beam's progress in a simple geometrical manner.
