Asked by maham237 @ in Physics viewed by 283 People
When a 45-kg person steps on a scale in an elevator, the scale reads a steady 480 N. Which of the following statements must be true?
Answered by maham237 @
Answer:
The elevator is accelerating upwards.
Explanation:
The scale should read the weight of the person, which is approximately 450N. Since the scale reads a higher value, the elevator must accelerate upwards to increase the normal force on the scale.
