Homework Help Overview

The original poster presents two questions: one regarding the measurement of the perihelion advance of Venus, and the other concerning the behavior of a pendulum in a falling elevator. The subject areas include celestial mechanics and classical mechanics.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Some participants question the relevance of the questions to the forum's focus, while others suggest that the problems may relate to concepts in relativity and spacetime. There is also a mention of considering factors like air resistance in the pendulum scenario.

Discussion Status

The discussion is ongoing, with participants exploring the appropriateness of the questions for the forum and considering various factors that may affect the answers. There is no explicit consensus on the direction of the discussion.

Contextual Notes

One participant notes that the questions may be homework-related and suggests posting them in a different forum. The original poster expresses uncertainty about the categorization of the questions.

URGENT: Have 2 questions

I got 2 questions, if anyone can answer one or both of them, ill appreciate it. thanks!
8. Why is it difficult to measure the perihelion advance of the planet Venus?
9. You are in an elevator at the top of the CN tower. You have a pendulum
and allow it to oscillate. The elevator falls to the ground after someone
cuts its support cables. What does the pendulum do? Ignore the air
resistance acting on the pendulum and the elevator.

If these are homework problems, you should post them in one of the homework forums, not here (they have nothing to do with relativity, anyway).
 
i thought these questiosn belonged to the relativity section bout space time and such...sry
 
I believe u would need to consider air resistance and the position at which the pendulum was at.
