Answer:
The tangential velocity for the cars are approximately 2.3 m/s
Explanation:
The given parameters are;
The radius of the Texas Star Ferris wheel, r = 65.8 mete secondsrs
The time it takes the Ferris wheel to go round once = 180 seconds
The angular velocity, ω = Change in angle rotated/(Time duration of the change)
ω = Δθ/Δt = 2·π/180
The tangential velocity for the cars, 
= ω·r = 2 × 3.14/180 × 65.8 ≈ 2.3 m/s
The tangential velocity for the cars, ≈ 2.3 m/s.
The correct answer is C, right-side up and smaller.
It is the most common example of spherical mirrors. The inside of the spoon acts like a concave mirror and the back side of it like a convex mirror.
A convex mirror always forms a real and diminished image. That is, the image formed is erect or right-side up and smaller in size. Therefore, Lin Yao should describe her reflection on the back side of the mirror to be right-side up and smaller.
The Earth's rotation does, like a basketball spinning
on the tip of Kobe Bryant's finger.
Since the Earth is somewhat bigger than a basketball,
it takes almost 24 hours to do one complete spin.
The sun can only light up 50% of the Earth at a time.
As the Earth spins, it moves you and me in and out
of the lighted half. Any time we're not in the lighted
half, we describe our situation as a "night" status.
