At the bottom of the circle, the ball is being pulled upward by tension in the rope and downward by its own weight, so that the net force on it is
∑ F = 450 N - (0.75 kg) g = (0.75 kg) a
where a is centripetal acceleration. At this maximum tension, the ball has a maximum centripetal acceleration of
a = (450 N - (0.75 kg) g) / (0.75 kg) = 590.2 m/s²
Then its maximum tangential speed v is such that
a = v² / (1.0 m)
⇒ v = √((1.0 m) a) ≈ 25 m/s

Pollination occurs when a pollen grain lands on <u>a reproductively mature stigma</u>.
What is pollination?
Pollination <u>is the act of moving pollen grains from the male anther of a flower to the female </u><u>stigma</u>, or, pollination is the movement of pollen from an anther of a plant to the stigma of a plant, allowing later fertilization and the formation of seeds, most frequently by an animal or by the wind.
Pollination, <u>which is most frequently accomplished by an animal or the wind</u>, is the movement of pollen from an anther of a plant to the stigma of a plant in order to later enable fertilization and the development of seeds.
