To solve this problem, we use this formula:
s = rθ
where
s is the arc length or in this case, the distance traveled by a point of a wheel
r is the radius of the circle or the wheel
θ is the subtended angle or the angle of rotation of the wheel
Plugging in the given values and converting degrees to radians
s = 22 *128 (π/180)
s = 49.15 cm
Answer:
I think it's B
Explanation:
sorry if I got it wrong TvT
mass lol ion kno man can i have the answer choices
-Synodic period is the period of celestial bodies observed on the moving planet(mostly earth)
Sideral period is the period comparing to the fixed stars without motion of the earth involved.
(I will explain the second question with an example, so it's easier to understand)
-For Sideral month for example of the moon it cactually complete one revolution in around 27.3 days.
However, since the earth moves, for us it took some more time to see the moon the same as before (fullmoon to fullmoon) again. That make synodic month of the moon to be around 29.5 days.
