They're all copying
and pasting, Why is the
answer
Assuming an average weight of 80 kg/person, it would take the
weight of 100 people to separate spheres?
About this. In 1656, Otto von Guericke of Magdeburg presented
his invention, a vacuum pump, through a demonstration that became a
popular sensation. A metal sphere made of two hemispheres (now
known as the Magdeburg hemispheres) was evacuated, so that a vacuum
would hold the two pieces together. Von Guericke would then have
several horses (by one account, 30 of them, in two teams of 15)
pulling, unsuccessfully, to separate the hemispheres. The
demonstration would end with the opening of a valve that removed
the vacuum and allowed the hemispheres to separate. Suppose that
the diameter of the sphere is 1 m and the sphere is completely
evacuated. The sphere is hung from the ceiling and you pull the
other half with the force of your body weight. Will the hemispheres
come apart? Support your answer with calculations.

The answer was different.
I'd like you to write a little better. I don't know some
words.!!
