optimism
Explanation:
optimism is not one of the Big five
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
The correct answer is d hope i could help

Dilation involves changing the size of a line segment
The scale factor is 2
From the question (see attachment), we have the following side lengths



So, the scale factor (k) from AB to A'B' is calculated using the following scale factor formula

This gives

Divide 2.5 by 1.25

Hence, the scale factor is 2
