Individual molecules bounce off each other like billiard balls in every direction thousands of times per second. The rate they "fall" isn't a significant factor. Warmer air wants to rise because it's lighter, colder air wants to fall cause it's heavier. It tends to move in ci...
If heavier bodies are attracted more strongly by the earth, why don't they fall faster than the lighter bodies? Why can't a white dwarf have a mass greater than 1.4M? Why is a larger nucleus generally less stable than a smaller nucleus? Why do objects float in liquids denser than thems...
There are a number of factors that can cause PVC (polyvinyl chloride) pipes to crack over time. One of the most common causes is physical damage, such as scratches or impacts from heavy objects. In addition, PVC pipe may lack sufficient support within its surroundings, resulting in increased ...
Do clouds float or fly? Even though a cloud weighs tons, it doesn't fall on you because the rising air responsible for its formation keeps thecloud floatingin the air. The air below the cloud is denser than the cloud, thus the cloud floats on top of the denser air nearer the land su...
Another way is to get a DEXA scan.In the above photo, I’ve gained 70 pounds, going from 130 to 200 pounds. My bones became denser and heavier, but they didn’t get thicker. The DEXA scan still shows that I have unusually thin bones. ...
Why do objects float in liquids denser than themselves? All atoms have moving electric charges. Then, why aren't all materials magnetic? We are made of atoms that contain electric charges. Why we do not feel any electric force in our daily life? Explain why the entropy of a black hole...
Why do objects float in liquids denser than themselves? Why is it important to use the same balance when making several mass determinations in an experiment? What are SI units explain? Why do we weigh more at the poles? Explain the difference between fundamental and derived units and give...
This layer is so much denser and heavier than other ocean water that if flows right down the slopes o f the ocean floor and gains more and more speed as it moves along. Then it's just like the winds blowing across the desert picking up sand from one place and moving it along and ...
