Mixing an acid and a base
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
Foreshadowing is the literary technique that is used to make predictions about the events that would still occur in a work of fiction by making use of hints.
As a result of this, an author can make use of some elements such as:
- Dialogue
- Motifs
- Symbols
- Metaphor, etc
Please note that your question is incomplete and therefore i am giving you a general overview that should help you arrive at the right answer.
Mood is the general feeling that a reader gets when reading a literary piece.
As a result of this, an author can make use of descriptive words to show the mood of an impending danger. Some sentences that can display this are:
- "Remember the terrible event that occured two years ago? It could happen again!"
- "I don't want my daughter to find out I am not her real father as she could run away!"
