Answer:
The Machine exerts a force of 9N.
Explanation:
Initial velocity (u) = 0 m/s
Final velocity (v) = 30 m/s
Time (t) = 0.5 s
Acceleration (a) = (v-u)/t
= (30-0)/0.5 m/s²
= 30/0.5 m/s²
= 60 m/s²
Mass = 0.15 kg
Force = Mass*Acceleration
= 0.15*60 N
= 9 N

The correct answer is B. Difficult
Explanation:
The temperament includes the particularities in behavior, reactions and emotional responses that are linked to the personality of an individual. Temperament is classified into three main categories: easy, difficult or slow-to -warm.
-Easy temperament is characterized by adaptability to new situations, positive mood/reactions, and regular body functions.
- Difficult temperament is characterized by irregular body functions, negative reactions and mood, and slow adaptability.
-Slow-to-warm temperament is characterized by few reactions, negative mood and different degrees of adaptability.
In the case of Nathan, his temperament can be classified as difficult temperament because he shows irregular body functions (sleep and feeding schedules are irregular), negative mood and reactions (he responds with tantrums and loud cry) and he seems to have difficulties in adapting to changes.
