Have 2 Questions: Measure Perihelion of Venus & Pendulum in Elevator

  • Thread starter leafvillage
  • Start date
In summary, the conversation discusses two questions, one about measuring the perihelion advance of Venus and the other about the behavior of a pendulum in an elevator falling from the CN tower. The speaker also mentions that these questions may be related to relativity and apologizes for posting in the wrong section.

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
 
  • #4
I believe u would need to consider air resistance and the position at which the pendulum was at.

What is the perihelion of Venus and how is it measured?

The perihelion of Venus is the point in its orbit where it is closest to the sun. It is typically measured using the concept of the "perihelion shift," which is the change in the angle of the planet's orbit over time. This can be observed and calculated using telescopes and advanced mathematical equations.

What is the importance of measuring the perihelion of Venus?

Measuring the perihelion of Venus is important for understanding the planet's orbit and its relationship with the sun. It also provides valuable data for studying gravitational forces and planetary motion, and can help to refine our understanding of the laws of physics.

How can a pendulum be used to measure the perihelion of Venus?

A pendulum can be used to indirectly measure the perihelion of Venus by measuring the effects of gravity on its swing. As the planet's orbit changes, the gravitational force exerted on the pendulum will also change, causing variations in its swing. By tracking these changes over time, the perihelion shift of Venus can be calculated.

Can the perihelion of Venus be measured from Earth?

Yes, the perihelion of Venus can be measured from Earth using advanced telescopes and mathematical calculations. However, this process requires precise and accurate instruments, as well as a deep understanding of orbital mechanics and gravitational forces.

How does the pendulum behave in an elevator and how does it affect the measurement of the perihelion of Venus?

In an elevator, the pendulum will be affected by the acceleration and movements of the elevator. This can cause variations in its swing, making it more difficult to accurately measure the perihelion shift of Venus. To minimize these effects, the pendulum should be placed in a stable and controlled environment, such as a laboratory.
