Answer:
Consistency paradox is the observation that a human being’s personality tends to remain the same over time, while their behavior can change in different situations.
Many personality characteristics are relatively constant throughout a person's life, but people can act in all sorts of ways (even ones that seem to be opposite of their personality) in different situations. For instance, even the most even-tempered and easy-going person can be driven to violence when put under enough stress or pressure.
Answer:
25 m
9.9 m/s
22 m/s
Explanation:
m = Mass of ball
v = Velocity
g = Acceleration due to gravity = 9.81 m/s²
Applying conservation of energy

The height above the ground is 5.09683+20 = 25.09683 m = 25 m

The ball's speed as it passes the window on its way down is 9.9 m/s

The speed of impact on the ground is 22 m/s
The three things that are necessary are power, a force, and movement in the opposite direction of the applied force.
