Compute each part of given question:

Question: A 70.0-kg person stands on a scale in an elevator.

Part I: What does the scale read (in N) when the elevator is at rest?

Part II: What does the scale read (in N) when the elevator is climbing at a constant speed of 3.0 m/s?

Part III: What does the scale read (in N) when the elevator is descending at 3.0 m/s?

Part IV: What does the scale read (in N) when the elevator is accelerating upward at 2.7m/s²?

Part V: What does the scale read (in N) when the elevator is accelerating downward at 2.7m/s²?

I need expert help to solve the above question and express your answer using two significant figures.
