In summary, it is not possible for any object to orbit the Earth in less than 80 minutes due to the Earth's gravitational pull. This is because as an object gets closer to the Earth, its speed increases due to the pull of gravity, but it eventually reaches a point where it cannot go any faster without leaving the Earth's orbit. There are no exceptions or special circumstances where an object could orbit the Earth in less than 80 minutes, and it is unlikely that advanced technology or future developments could make it possible. The Earth's rotation also does not have a significant impact on the orbital time.

"Describe the objective, apparatus, and results of the cavendish expirment?"
----------------------------------
Question2: Prove (using algebra) that it is impossible to go around (orbit around) Earth in less than 80 min..

I honestly have never heard of this... can some one explain it to me? or give me some links about it?

re Cavendish expt just search on the web.
re 2nd part:
Do you know how to use F = ma for an object going in circular orbit about the Earth?
 

1. Can any object orbit the Earth in less than 80 minutes?

No, it is not possible for any object to orbit the Earth in less than 80 minutes. The fastest orbital speed around the Earth is approximately 17,500 miles per hour, which would take about 90 minutes to complete one orbit.

2. What is the main factor that makes it impossible to orbit the Earth in less than 80 minutes?

The main factor that makes it impossible to orbit the Earth in less than 80 minutes is the Earth's gravitational pull. As an object gets closer to the Earth, its speed increases due to the pull of gravity. However, at a certain point, the object will reach a speed where it cannot go any faster without leaving the Earth's orbit.

3. Are there any exceptions or special circumstances where an object could orbit the Earth in less than 80 minutes?

No, there are no exceptions or special circumstances where an object could orbit the Earth in less than 80 minutes. The laws of physics govern the orbital speed of any object around a larger body, such as the Earth, and these laws apply to all objects regardless of their size or composition.

4. Could advanced technology or future developments make it possible to orbit the Earth in less than 80 minutes?

It is highly unlikely that advanced technology or future developments could make it possible to orbit the Earth in less than 80 minutes. While technology has advanced significantly, the laws of physics still apply and cannot be overcome by technology alone.

5. How does the Earth's rotation affect the time it takes to orbit the Earth?

The Earth's rotation does not have a significant impact on the time it takes to orbit the Earth. While the Earth's rotation can provide a slight boost to the speed of an object in orbit, it is not enough to make a significant difference in the time it takes to complete one orbit.
