Taking down sheet rock in a house built in 1949 should I be concerned about asbestos?
Don't sit at home worrying. She will be there having a wonderful time. I'm sure she is wise and has heard the horror stories. There are thousands of tourists there all the time . They don't get into trouble they explore the sights shop and laze about the fabulous beaches and get to see another culture. I got sick when I went probably from the water which I tried to be careful it only lasted 24 hours but was really horrible perhaps she can take something from the chemist to settle the tummy incase of this. make sure it is properly labelled .
Gravity is caused by the atraction of two bodies of matter to one another. There is no energy expended that we can measure, there is also no heat caused by it. My idea says that the energy of atomic attraction in the atoms caused by the pos neg forces from electrons and protons expands exponentially and is focused through the neutrons rendering it neutral.
gravity is the curvature of space-time. The more mass an object has, the more gravity it has, the bigger the curvature. Imagine a rubber sheet with a bowling ball on it. The sheet is space-time and curves around the ball. No energy necessary.
